本文报导了稀土 X 射线增感屏用荧光粉 LaOBr:Tb 的制备工艺及其发光性质,着重报导了解决其抗潮解问题,以求得推广应用。LaOBr:Tb 完整的结晶及辅以双亲性高分子化合物包膜是能抗潮的主要因素,本文从实验中得以说明。
In this paper, the preparation and luminescent properties of LaOBr: Tb phosphor for rare earth X-ray sensitized screens are reported. The problems of anti-deliquescence are mainly reported in order to promote its application. The complete crystallization of LaOBr: Tb and the encapsulation of the amphiphilic polymer compound are the main factors that can resist moisture. This article is illustrated from the experiment.
