| 摘 要： | 采用光谱拟合胶ＣＩＥ色度计算方法，研究蓝宝石光学吸收谱各吸收带与颜色主波长的关系。结果表明：蓝宝石的颜色主要与Ｆｅ＾２＋／Ｔｉ＾４＋对和Ｆｅ＾３＋离子相对浓度有关，随着Ｆｅ＾２＋／Ｔｉ＾４＋对和Ｆｅ＾３＋离子的浓度比值由高到低，颜色主波长由小到大连续变化，即颜色呈现紫－蓝－绿－黄变化。

| Abstract: | The relations between absorption bands and color of sapphire are systematically studied through the methods of absorption spectra seperating and simulating and the CIE color calculating theory. It shows that the color of sapphire is related to the relative concentrations of Fe2+/ Ti4+Pairs and Fe3+, with the ratio of concentrations of Fe2+ / Ti4+ to Fi3+varying from high to low, the colors of sapphires are gradually change from violet, blue, green, and to yellow. |
