luminous glow produced low levels of sand

When SrAl2O4 365nm UV excitation light when , Eu2 + 4f → 5d transitions produce . Auxiliary active ions Dy3 + and adding , changing the shape of the lattice , the lattice distortion , resulting in the impurity level ( trap level ) , photoluminescent paint level is mainly produced by the D to join , and replaced by Sr2 + Dy3 + cause the generation of holes , the trap level is relatively uniform holes produced by the donor level . The energy level in the excited state of Eu2 + ground state level and between levels . When an electron is excited from the ground state to the excited state , the part of the electronic transition back to the low level photoluminescent sheet, another part of the electrons through the relaxation process is stored in the trap energy level , when the electron trap levels absorbed energy, the re- stimulated Back excited states , transitions back to the ground state energy and light.

Synthesis of a luminescent material with considerable adaptability

For high-temperature solid-phase luminescent particles coarser prepared by ball milling crystal is destroyed, so that the significant decline in brightness shortcomings , people developed the " combustion " preparation techniques . Kingsley , etc. A certain amount of Al (NO3) 3.9 H2O, Sr (NO3) 2.4 H2O and urea , dissolved in a small amount of water , and the resultant solution was placed in a constant temperature of about 500 ℃ horse boiling furnace. Initially solution was boiled , then photochromic masterbatch, decomposition , accompanied by a large amount of gases (mainly NO and NH3). Then start blistering , swelling, the bubble burst and burned , emits white light . The resulting product is a porous foam SrAl2O4, single phase product , photoluminescent exit signs material synthesized with considerable adaptability of the gas generated in the combustion process can restore the Eu3 + Eu2 +, without the need to restore the protective atmosphere . This approach can significantly reduce the furnace temperature , a meaningful synthesis of energy-efficient .

Luminescent ceramic may also be used for building a variety of decorative designs

Within a variety of low nighttime outdoor lighting, decorative lighting and various nameplate. Such as family, hospital wards and other low-intensity lighting at night, building corridors, rooms nameplate, cinema seat licensing, security doors, electrical switches and darkroom lighting power, luminous slippers, luminous phone handles like.
Photoluminescent Ceramic may also be used for building a variety of decorative designs, such as: Glow plaster ceilings, hanging shelf, neon decorations, decorative painting, luminous tiles. All kinds of watches and clocks, instruments, instrument dial and pointer. Exquisitely luminous (Phosphorescent Ceramic, glass, acrylic, polyester) crafts, glowing pearl, luminous sculptures, murals, etc., can be applied to screen printing or leakage printing plate printing method luminous paintings with a variety of different effects. For luminous marble (granite), luminous paint, road signs, road marking reflective light emitting (signs) paint, lights and so on.

Photoluminescent Ceramic is the kind of high-purity, high-tech advanced materials

Photoluminescent Ceramic rare earth materials is intensified by the high temperature and pressure treatment from a high-purity, high-tech advanced materials. It can absorb sunlight or other light scattering, absorption can occur STORING after activation, and intense light, the light-emitting time of up to over 12 hours, and the light emitting properties can be repeated again, maintaining a glow effect for 15 years, so everything is bright Yongxiang . luminescent films ceramic can be incorporated into paint or resin coating or injection molding.

photoluminescent pigments color used in the general safety are the following

photoluminescent pigments color used in the general safety are the following: 1 , Red: used to mark the ban , stop and fire , such as lights, signal flags , emergency stop buttons on the machine are to indicate "No " message in red. 2, yellow : attention to danger signs . Such as " Beware of electric shock" , " pay attention to security" . 3 , green : to mark the safe thing. Such as " In this job ," " grounded " and so on. 4 , Blue: used to mark the enforcement , such as " must wear helmets " and so on . 5 , Black: used to mark images, text and glow in the dark material technology in line geometry . Luminous luminous graphic signs are generally used to warn people not to get close to dangerous places. To ensure the safe use of electricity , must be in strict accordance with the relevant standards using color logo and graphic signs

Fluorescent pigments in the field of automation and high-tech lead is used for the optical identification

In the field of automation and high-tech fields, fluorescent pigments are also used for optical identification and the like. For example, the standard code, tracking and sorting files, e-mail and other rescue. Dazzling fluorescent color in almost all other areas in the use of color are more and more applications. For example, a variety of children's equipment and toys, modern art, arts and crafts, fashion, and so on.
1, used in plastic products
In the use of plastic products are: injection molding, extrusion, blow molding blow molding, kneading and the like.
The main principle is at a high temperature molten thermoplastic fluorescent pigment dispersion (dissolution) in plastic products.
Product fluorescence with a fluorescent pigment itself fluorescence, fluorescent pigment compatibility and plastic products, the operating temperature and the process time and other factors.
2, used in coatings, paints, inks, paste the
Use thermosetting fluorescent pigment: Following coatings, paints, inks, color paste production formula, a fluorescent pigments manufacturer and other materials are added to the high-speed dispersion kettle, high-speed dispersion, preferably also need to be sanded (or three stick grinding) . Dispersion (sand) be adjusted after the paint (or varnish). Finally filtration, packaging.

glow in the dark stones the construction requirements

1, before construction to be coated on the surface glow in the dark dye‍ treatment, to no oil, no rust marks no dust, clean environment during the construction requirements and have ventilation and air dust collector equipment and other facilities to ensure the construction quality. 

2, the coating process: You can spray or brush. 

3, the paint must be fully Stir well before use,photoluminescent river rock the construction can be carried out with special thinner to application viscosity. 
4, after the substrate handling, can brush primer, primer to be completely dry and then brush finish.‍

Phosphorescent sand in the field with a green fashion show

Phosphorescent sand in the field with a green fashion show to enjoy the interpretation of the theme . Waste CD, waste plastic bags, expired Newspapers ...... these people's lives everywhere waste materials in their ingenuity wonderful to become both under the original sense of fantasy and romantic atmosphere of the fashion Glow in the dark pebbles  suppliers  bold colors with with very life breath of life items of integration, one youthful face constantly surprises. Kids handheld LED light bulb lighting handmade lanterns, to witness this moment. Holding a plastic shopping bag, tie wire and light-emitting diodes made photoluminescent pigments , compact switch fixed with tape to pick the pole . "Now the children have been very difficult to have the same look as our childhood experiences starry sky , and children together to do this lantern is hoped that she can never forget the concept of energy conservation in mind , I hope the stars are no longer just child's dream .
