For instance , the phosphor on a crt screen needs to be constantly reactivated by an electron beam in order to remain illuminated 例如，阴极射线管荧光屏上的磷光体为了保持它激发光状态，需要用电子束不断地再激励。
The adulteration of bi3 sm3 + can increase the fluorescent intensity , while dy3 + > gd3 la3 + reduce it ^ specially dy3 " 1 " 掺杂微量bi和sm使余辉强度的提高，但dy 、 la和gd则使磷光体余辉强度有所降低，其中dy较为明显。
