摘要: 论述了萤石的物理性质及其发光性(荧光和磷光)。对磷光产生的机理进行了论述,认为晶体结构缺陷和晶体结构中的发光稀土元素是产生磷光的原因。介绍了“夜明珠”(发光石)的鉴定方法,并针对目前在发光石鉴定中存在的无序状况,建议国家建立“夜明珠”的鉴定标准,以规范“夜明珠”市场。

Abstract: The physical properties and the luminescence(fluorescence and phosphorescence) of fluorite are discussed in the paper.The phosphorescence is produced by the defects of crystal structure and the luminescent rare-earth elements in the crystal structure.The identification of the "night luminescent bead"(luminescent stone) are analysed.And at the same time,in view of the present confused situation in the identification of "night luminescent bead"(luminescent stone),the proposal of the national standard about "night luminescent bead" is put forward in order to normalize the market of "night luminescent bead".
