| 摘 要： | 俄罗斯水热法合成祖母绿是珠宝界较关注的产品。选用5粒俄罗斯水热法合成祖母绿样品进行了常规宝石学特征测试、电子探针成分分析、红外吸收光谱和紫外-可见吸收光谱测定。结果表明,俄罗斯水热法合成祖母绿样品以低碱、富Fe与Cr为特征,折射率和相对密度明显偏高,红外吸收光谱特征峰出现在4 052 cm-1附近;俄罗斯水热法合成祖母绿样品的致色元素为Cr与Fe。同时,对比分析了俄罗斯、桂林水热法合成祖母绿样品和天然祖母绿样品的宝石学特征。

| Abstract: | The Russian hydrothermal synthetic emerald has caught the attentions of the gemmologists.Five Russian hydrothermal synthetic emerald samples are tested for the conventional gemmological characteristics,chemical compositions,infrared absorption spectra and ultraviolet-visible absorption spectra.The results show that the Russian hydrothermal synthetic emerald samples are characterized by low alkali,rich Fe and Cr and higher RI and SG.In addition,4 052 cm-1 is the characteristic absorption peak of the Russian ... |
