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.
