摘要
通过对新疆电气石用６０Ｃｏγ射线辐照、热处理可使之变色，应用ＸＲＤ、ＸＲＦ、吸收光谱实验，得出电气石改变颜色主要由ｂ位Ｆｅ２＋和Ｍｎ３＋电子的ｄ－ｄ跃迁相应的１３８００ｃｍ－１和１９５００ｃｍ－１谱所决定。
The radiation-induced colour change of tourmaline from Altayin Xingjang wad studied by heat treatment, X-ray diffraction, X-ray flouorescencespectrometry, absorption spectrometry. It was shown that the colour change effectconditioned by the change of 19500 cm-1 and 13800 cm-1 spectra ascribed to d-d transition of Mn3+ and Fe2+ in b site.
