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.
Application
The new type of pigment is used for many very different technical and artistic purposes due to its characteristics. It can be used in manufacturing paint; ink; plastic; rubber and films etc. It is completely safe for the application in consumer products such as clothing; shoes; caps; toys; stationery goods; watch; switch; novelties; fishing tools and sporting goods. It has good effects in the fields of building; decoration; traffic vehicle; military installations; fire emergency system. It is especially suitable for the production of long afterglow safety products such as warning; mandatory and escape-route signs.

Note:
1)The above technical data was obtained through test in accordance with DIN67510 Part I method.
2)The after-glow time refers the time it takes for the luminance to reduce to 0.32mcd/m2 from the
time when the light exciting source was moved.
3)Other larger or finer particle sizes are also available as to customer's actual application need.
4)All types can be coated for waterbased application.
5)ZSG Series are ZnS pigment.
