Shenzhen city Baoan District Songgang Huayang Technology materials firm   

Mainly for the rare earth doped aluminate long afterglow phosphor (also known as long afterglow luminous powder, ultra light storage luminous powder, phosphor composition etc.), can be expressed as: Al2O3 (Sr, Mg, Ca) O: (Eu, La, Dy) B. With light absorbing - strong light storage and luminescence capability, through the absorption of ultraviolet light or visible light, the conversion of light energy stored in the crystal lattice, in the dark can be converted to light energy and light energy. Average particle size is 5~10 micron, the sunlight or indoor light irradiation 10~30 minutes after the initial 00~16500mcd/m2, brightness, light duration?
