Introduction:

Our photoluminescent pigment is made from the rare earth elements such as alkaline-earth aluminate or silicate compounded by high-temperature solid phase reaction, is a kind of novel, long-efficiency and environmentally friendly material invented in recent years.

Characteristics

Short Storing-light time:10-20 min;
Long afterglow time: Over 12 hours

Day color: Light yellow green powder; Off-white powder
Glowing color: Yellow-Green, Blue-Green,Sky-Blue, Violet, White, Orange-Red,etc.
High luminance:40-90mcd/square meter after 60 min;
Wide excitation wavelength:200-450nm,e.g. visible light, Lamp light, UV light;
Life time: more than 10 years

Safety: non-toxic/non-radioactive/nonexplosive/incombustibly/pro-environment

Long after glow time, high luminance (over 10 times than traditional pigments: ZnS)

Good ultraviolet radiation excitation effect (200-450um)

Advantages:

1. Photoluminescent pigments are a new type of long persistence phosphorescent pigment of alkaline earth aluminate activated by rare earth ions.

2. 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.
3. The brightness and length of persistence time are more ten times than those of the conventional phosphor of zinc sulfide.

4. The material itself has nontoxic and harmless and free from any radioactive additives.
5. It has good stability and weatherability. Excitation and emission can be repeated indefinitely.

Usage:

1. It could be used in many transparent or translucent mediums, such as plastic, paint, glaze, ink, glass, printing slurry etc. to produce luminous products.

2. With the good indicating and beautifying effect in darkness, it could be widely used in emergency signs, pass way signs, switches, enamel nameplate, road signs, toys, handicraft, clock, etc.

3. Apply in Industry: building; decoration; traffic vehicle; military installations; fire emergency system ,etc
