Photoluminescent Pigment For Glass
Our Photoluminescent pigments are a new type of long persistence phosphorescent pigment of alkaline earth aluminate activated by rare earth ions. The main characteristic of this material is the particular structure of its crystal with the strong capacity of absorbing-storing-emitting light. After absorbing varieties of visible lights (suitable for common light in room) , it can glow for more than twelve hours in the dark. The brightness and length of persistence time are more tens times than those of the conventional phosphor of zinc sulfide. The material itself has nontoxic and harmless and free from any radioactive additives. It has good stability and weatherability. Excitation and emission can be repeated indefinitely.
