1. Nontoxic and nonradiative, harmless to humans and environment.

2. More excitation light source permitted. As long as the light intensity reaches 25LX, it can be used as an excitation light source. In general buildings, the light intensity can get to 500LX and above. Therefore, sunlight, general lighting, surrounding stray light can be used as excitation source.

3. Longer glowing time: It’s able to produce high-luminescence afterglow in the next 12 hours after 10 ~ 20 minutes of exposure under the light, which is 30 times of traditional luminous pigment which produced by phosphor.

4. Outdoor applicability: It has excellent physical and chemical properties and can be used outdoors or in extreme environment. It can resist ultraviolet and maintain its performance basically after thousand hours of exposure to 300W high-voltage mercury lamp. It demonstrates sound ability in resisting chemical corrosion and can be applied in a wide temperature range (-20 to 500°C).

5. More colors available: yellow-green, blue-green, red, blue and purple glow powder.

6. Long service life (>15 years) and its characteristics (light absorption, storage and radiation) can be infinitely reused.

7. It can be processed into products in different grain sizes (0.5 - 200 um) corresponding to different industrial requirements.
