Photoluminescent Pigment

Introduction

The rare earth-activated alkali earth aluminate-Strontium(Sr) photoluminescent pigment, with the chemical formula of MO·aAl2O3·bSiO2·cL: Eu2+Dy3+, compounded by high

temperature solid phase reaction, is a novel, durable, effective, and environmentally friendly material.

Luminescent Mechanism:

When exposed to certain wavelength of light, material was activated after the groundstate electron in the molecule

absorbs energy, a transition is made to high energy track. However, as high energy orbit is not stable, electronic

spontaneously transit back to the original track while emitting energy in the form of light.

When there is light again, it stores energy again. So the photoluminescence process is circulatory.

Characteristics:

1. Initial High Brightness: in sunlight or under light radiation for 10 minutes, the intial brightness can reach more

than 10000mcd/m2

2. Long afterglow time: absorb light during the day, glow over 10 hours in the dark, its luminous intensity and the

maintenance time is 30 times more than traditional luminescent material.

3. Safety and Environment Friendly: non-toxic, harmless, non-inflammable, non-explosive, and radiation-free;

4. Weathering good: material stability and weathering resistance, excellent in outdoor use with no limitation with

unlimited glow cycles.
