luminescent material

Aluminate has been used widely as host material of laser and luminescent material because it it has a good temperature conductivity, mechanical strength and chemical character which can dope different rare elements easily.

铝酸盐由于具有优良的导热性、机械强度以及良好的化学性质，易于掺入不同的稀土离子而获得不同颜色的光，因而被广泛地用作激光和发光的基质材料。

Long afterglow luminescent material is capable of absorbing sunlight or ultraviolet ray and storing energy during the day, and releasing the energy in the form of visible light once the irradiation light is cut.

长余辉发光材料是白天能够吸收光能，并将光能储存起来，当光线停止照射后能将储存的光能以可见光的形式释放出来的一种新型绿色能源材料。
