摘要
针对中国河北阜平地区发现的稀有珍贵宝石品种———变色萤石,利用电子探针、双聚焦电感偶合离子体质谱仪、X射线粉晶衍射、阴极发光、热发光、红外光谱、拉曼光谱等现代测试手段,研究了该变色萤石的宝石学特征,并根据化学成分和光谱特征,初步探讨了其变色成因,该变色萤石在黄橙区的578nm吸收带主要与2F i*色心有关,对变色起作用的元素可能是Y、Sr、Nb、Sm、Fe、V。
A rare and precious species of gemstone-fluorite with alexandrite effect( FAE), presents in Fuping of Hebei province. It is bice in the sunlight and magenta in filament lamplight. The gemological characteristics were investigated systematically by using modem test methods such as EMPA, ICP-MS, X-ray powder diffraction, cathode luminescence, natural thermal luminescence, iufrared spectrum, laser raman spectrum, etc. , And the origin of its col- or changing has been discussed primarily according to the chemical component and spectrum characteristics ,which mainly attributes to the 2Fi * color center,and the possible influencing elements are Y,Sr,Nb,Sm,Fe and V.
