山东黄色蓝宝石紫外-可见吸收光谱表征

ULTRAVIOLET-VISIBLE ABSORPTION SPECTRA REPRESENTATION OF YELLOW SAPPHIRE FROM SHANDONG PROVINCE IN CHINA

蓝宝石的颜色成因一直是矿物和宝石学者研究的重点,文章运用矿物物理学等有关理论对山东黄色蓝宝石的紫外—可见吸收带成因归属进行了分析和探讨,结果得出,山东黄色蓝宝石呈色主要是过渡金属离子的d—d跃迁、Fe2+—Fe2+耦合对、Fe2+—Fe3+耦合对和Fe2+—Fe3+电荷转移跃迁共同作用。

The color genesis of sapphire is always the researching emphasis of scholars. The genesis of UV-VIS absorption band of yellow sapphire are analyzed and discussed by using the theories of physics of minerals and inorganic materials. The color of sapphire from Shandong province is the result affected together by d-d transition of transition metal ions, Fe^2+ —Fe^3+ coupling pair, Fe^2+ —Fe^2+ coupling pair and the transition of charge transfer.
