摘　　要：通过研究红宝石中Cr、Fe含量的变化对其吸收光谱以及颜色表征的具体影响,发现当Fe^(3+)/Cr^(3+)含量比接近0时,红宝石多呈紫红色,明度值中等偏高,且荧光强;当Fe^(3+)/Cr^(3+)含量比接近1时,红宝石紫色等杂色不明显,呈较为纯正的红色,明度值及荧光强度降低;当Fe^(3+)/Cr^(3+)含量比接近2时,红宝石明度值升高,颜色呈带粉色调的红色,荧光强度弱。基于以上研究成果,对今后深入开展红宝石产地鉴定以及品质分级的研究,提供了一定的科学理论依据。The authors found that when the Fe^（3＋）/Cr^（3＋） content is close to 0, ruby is purple red, medium high lightness, and strong fluorescence;When the content of Fe^（3＋）/Cr^（3＋） is close to 1, ruby purple in the secondary color is not obvious, as the more pure red,and lightness and fluorescence intensity decreased;When the Fe^（3＋）/Cr^（3＋） content is close to 2, ruby lightness values increased, the color is pinkish red, the fluorescence intensity becomes weaker. Based on the above research results, this study provides a scientific basis for the further development of the identification of the origin and quality classification of the ruby.
