摘　　要：本文着重报导对采自我国不同地区和不同成因类型的23个天然萤石样品所进行的喇曼光谱测定和研究结果，大多数样品也同时显示发光谱。研究说明，萤石的喇曼图诺与其成因类型、样品的颜色，特别是所含稀土总量密切相关。低温有利于发光谱线的呈现，而高温则恰恰相反。Reported in this paper are the results of Raman spectral studies of 23 natural fluoritesamples of different origins from different locations in China. Most of the samples also display luminescence spectra. Studies indicate that the Raman spectra of fluorites are closely related withthelr genetic types, colors, especially the total amount of the REEs contained in them. Low temperature is favorable to the appearance of luminescence lines whereas high temperature just resultsin an opposite trend.
