摘要
综述了紫外-可见吸收光谱的产生机理和宝石的电子跃迁类型,介绍了紫外-可见分光光度计应用于宝石的测量方法和积分球附件的测试原理,总结了紫外-可见吸收光谱在质量鉴别和呈色机理方面的应用,比如红、蓝宝石,紫色翡翠等都可以得到较好解释,最后讨论了紫外-可见吸收光谱在宝石监测应用的局限和方向。
Generating mechanism of UV-Vis absorption Spectrometry and molds of electronic transition for gem were summarized.The application of ultraviolet-visible spectrophotometer in gem measuring and measuring theory of integrating sphere accessory were introduced.Research on quality discrimination and mechanism of colour generation by ultraviolet-visible spectrometry were summarized,such as ruby,sapphire and purple emerald etc.can get good explanation.Restriction and direction of UV-Vis spectrophotometer applying to gem measuring were discussed in the end.
