does not guarantee a night lighting Phosphorescent Ceramic

However, Shen Yongjia had a different opinion. "Based on its performance, luminescent sheets ‍powder luminous at night only last about four to five hours." Shen Yongjia said, from the continuous emission time, it does not Photoluminescent Pebble‍ guarantee a night lighting. 

In addition, he said, adding a luminous pink road signs only a faint green, can not achieve adequate lighting effect. "This suit is not installed street lights in the field road use, traffic can be set to identify the scope, not to put the car into the ditch." 

also pointed out that luminous paint painted road lane for the region, street lighting between the lane marking can be covered, the use of light-emitting powder coating can not. 

At the same time, cost and stability of the luminous road has also been Luminous sheet‍ questioned scholars. 

The key element of long afterglow luminescent powder is rare." Shen Yongjia said before the rare earth prices, the domestic price of 1 kg flour is about 1,000 to 2,000 yuan, and now the price should be higher. 

Efficiency luminous pink haze on cloudy days to absorb energy and how high? Absorption efficiency is not high enough in the circumstances, how to ensure continuous light at night?" Experts believe that the luminescence on the road should be photoluminescent pigment suppliers‍ further stability and luminous efficiency research and planning.

Starry fireflies 

Firefly light organs, the female end of the abdomen grows in three sections, from the appearance of just a layer of silver transparent film, which is fluorescent pigment. If this layer film opened under a magnifying glass, you can see thousands of photoluminescent pigment suppliers‍ light-emitting cells, then the following is reflective layer, a light emitting cells in peripheral nerve branches thick with fine small trachea and dense. The main material in the light emitting cells is luciferase and luciferin. When the fireflies start activity, rapid breathing, inhaling a large body of oxygen, oxygen through a small tube into the light-emitting cells with fluorescein in the cell plays a catalyst role in the interaction when luciferase, luciferin will be activated to produce bio-oxidation reaction led Pitt Yingying fireflies emit light belly to. Also, because the fireflies different respiratory rhythm, light and dark when they "flash signal" form. People After the study, the luminescence process, the column a simple formula: 

Luciferase role 

Luciferin + oxygen ─ ─ ─ ─ ─ → fluoresce 

Firefly luciferase in vivo is not inexhaustible, luminescent films‍ NA me many times that they constantly emit light energy is come from? The original energy from adenosine triphosphate (referred to as ATP), which is everything in vivo supply of energy substances. Firefly body with this energy, not only uninterrupted light, and the brightness is also strong. Only light-emitting structure can not be light, but also a brain systems regulate disposal. If an experiment, the removal of the head of fireflies, glowing mechanism loses effect. Countdown female abdominal section 2,3 entire section can be light, looks like for broadband-like, while the distal form only punctate light, it is both sides of the body section can also be seen from the back. Only males can shine distal abdomen, and the female abdomen distal same, also showed two spots of light. 

Egg, larva, pupa can shine. Eggs are not just given birth to luminous, but the approach of hatching from the egg shell outside the visible two points of light. Have proved that it is caused by the larvae in the egg shell activity, therefore, is actually the larvae have light hair formation. Larvae countdown end of the abdomen visible light emitter Section 2, but only two points of light hair, it can be seen from the back. 4-5 days after pupation, pupal abdomen on both sides of each end of a visible spot, but the pupae are doing cocoon sediment chamber, so it is not visible luminescence. 

Firefly luminous efficiency is very high, almost able to completely converted to chemical energy visible light, modern electric light efficiency several times to several times. As the light from the body of chemicals, therefore, fireflies emit light to light but no heat, though, does not produce a magnetic field, people call this light is "cold." As the fireflies light without radiant heat, physicists think that is very ideal lighting, because when things generally light, but also heat, such as lit candles. Another example is the lamp open - after light bulbs are also red hot. However, people do not need light fever, if it photoluminescent pigment suppliers‍ could not create the same heat as the fireflies light that would be ideal. Thirty years ago, it simulates the principle of creating a firefly glowing fluorescent (Fluorescent), the base - the upper reaches of this requirement. 

With the development of science, fluorescence applications are increasingly widespread. Check the food content using fluorescent bacteria containing explosive gas in the mine using fluorescent lighting in the arsenal of lights, LED underwater lights, and no not the fluorescence. American biochemist fireflies light emitting principle and mechanism, put forward the principle of electron transfer reactions, which can be explained by corrosion, photosynthesis, especially the development of the use of lasers, and therefore won the 1992 Nobel Prize in Chemistry. ‍

sparking a series of reactions luminescent sheets

microbial mischief: Australia emits blue fluorescence lake at night 

Australian photographer decorative aggregate‍ Phil Hart Victoria in the country recently captured a strange phenomenon, some people swimming at night in the Gippsland Lakes (GippslandLakes) swim, who went so far as to issue a touch of blue. 

Hart's friend nighttime swim in the lake, and when they stand up from the water, Phil shot these incredible pictures. He said: "It's like we're playing radioactive paint." These are just a chemical reaction called bioluminescence caused when naturally occurring micro-organisms in the water body being disturbed, this phenomenon occurs. 34-year-old Phil put away the camera, the shutter speed is slow, then the water constantly throwing sand and stones, sparking a series of reactions, while he try to capture more of this strange fluorescent screen. These pictures are very garden decorative stones‍ surprising, because when shooting them, the concentration of "luminous algae," the water of microorganisms large, so the picture looks quite spectacular. 

Phil said: "This scene is very spectacular and very rare in a company engaged in kayaking I work for a company as a project manager, the company has been up to in the Gippsland Lakes operating for 50 years, but nobody remembers once. seen so bright bioluminescence. "It is reported that forest fires and floods cause a lot of nutrients in the water available for microorganisms to survive. He said:. "Maybe later, I never see this scene of the phenomenon can be seen in blue here and use the camera to record my hands this golden moment, I feel very fortunate." 

Phil, who lives in Melbourne, said: "Although the bioluminescence is very conspicuous, but only the bright blue in the photo to see when I saw my first photo shoot, Photoluminescent Tumbled Gravel‍ I could not believe my eyes. , who was covered in water, emit faint blue light, looks very weird. "

Phosphorescent Ceramic Afterglow effect

Effects of the semiconductor light emitting afterglow phenomenon due to incident light, and the light emitting diode is a semiconductor light emitting phenomenon caused by the electric field. Photoinduced effect afterglow effect and has a decorative gravels‍ close relationship. Photoinduced effect refers to the valence band electrons are incident photon excitation, will jump across the forbidden band into the conduction band. If the conduction band electrons are excited back to the valence band and the transition will emit photons in the form of energy release, which is photoinduced effect, also known as: fluorescence effect. 

Photoluminescence phenomenon will no longer produce metal. Since the metal, the valence electron band is not filled, only fluorescent paint‍ low levels of electron excitation to the valence band energy level of the same. At the same valence band electron luminescent sheets transitions from the high energy level back to a low energy level, the energy released is too small, long-wave photons produced, far exceeding the wavelength of visible light. In certain ceramics and semiconductors, the band gap between the valence band and the conduction band clique, the excited electrons jump over the forbidden band from the conduction band, which is released back to the valence band of the photonic band in the visible wavelength exactly. Such materials are referred to: fluorescent material. 

decorative gravels Afterglow phenomenon

If the fluorescent material contains some trace impurities, and these levels of impurities located in the forbidden band, the equivalent of trap levels, 

After being excited from the valence band into the conduction band electrons, will fall into the trap levels. Because these are captured by the trap levels must first excited electronic trap levels out after the transition back into decorative gravels‍ the conduction band to the valence band, so they are incident photon excitation luminescence will be delayed for some time, the emergence of the so-called afterglow phenomenon. 

Afterglow generation principle 

Afterglow generation principle 

Long-lasting and can be divided into short afterglow afterglow, they are determined by the delay time. 

Is the photoluminescent material in the light emitting material (usually ultraviolet light, infrared light and visible light) emitting excitation irradiation. Relaxation time classified according to light, the photoluminescent material can be divided luminescent sheets‍ into two types of fluorescent materials and phosphorescent materials. They correspond to the above short and long afterglow afterglow. 

Photoluminescence mainly three-step process: 

1, the absorption of a photon; 2, the laser can be transferred to the fluorescent centers; 3, the radiation emitted by the fluorescent centers. 

Photoluminescent material is mainly used for display, imaging, lighting and everyday life. In everyday products, such as washing brighteners, fluorescent paint, fluorescent cosmetics, and so the use of the fluorescent dye a fluorescent material. Some lamp phosphor photoluminescent signs‍ materials are phosphorescent material, which can be made with high efficiency and high color rendering fluorescent lamps. 

luminescent sheets Experienced a long period of development

Trends 

Experienced a long period of development, long afterglow materials have been self-contained, with its own unique "charm" to emerge and show broad application prospects. Although research in this area is very active. However, decorative gravels‍ in its research and applications, there are still many problems to be solved. Long Afterglow luminescence mechanism is not very good for research, there are still many problems to be explained; matrix material and less active fluorescent pigments manufacturer‍ ions with a single selection; How to better synthetic methods such as sol-gel method instead of high-temperature solid-phase synthesis reaction is a serious problem ...... afterglow material because of its excitation in vitro in biological applications to avoid the effects of in vivo autofluorescence, luminescent sheets very biological reserve is expected to be applied to imaging. I believe that through control of material composition, structure, improved preparation process, long afterglow materials will be in more and more widely used.
