蓄光性荧光材料是经过紫外线的照射后发光的,在把照射的光源遮断后继续很长时间的自己发光的物质,我们称为蓄光性荧光材料。蓄光性料是经过太阳光、灯光等一切可视光照射后,吸收了光能,然后把这种能量在无光的情况下转换成光的形式慢慢的放射出来的一种蓄能性材料。这种材料永久的保持着吸收放光的功能。蓄光材料历史悠久。其中以硫化铅化合物系列的蓄光荧光材料最为有名。但是由于它的余辉时间只有短短的5至
Light-storing fluorescent material is a light-emitting material that emits light after being irradiated with ultraviolet light and emits light itself after a long period of time when the irradiated light source is cut off. We call this light-storing fluorescent material. Light storage material is through the sun, light and all other visible light irradiation, the absorption of light energy, and then this energy in the absence of light into the form of light slowly emit an energy storage material . This material permanently retains the function of absorbing light. Light storage material has a long history. One of the lead sulfide compounds series of light storage fluorescent material is best known. But because of its afterglow time only a short 5 to
