摘要
昌乐蓝宝石的呈色是过渡金属离子的ｄ－ｄ电子跃迁和电荷转移跃迁等因素共同作用的结果；蓝宝石呈何种颜色取决于蓝宝石晶格中Ｆｅ２＋，Ｆｅ３＋，Ｔｉ４＋，Ｔｉ３＋“等色素离子的含量，更取决于这些离子的相对含量，亦即Ｆｅ２＋／Ｔｉ４＋，Ｆｅ３＋／Ｆｅ２＋的比值．
The coloration of sapphire from Changle is caused as a result of the d-d electron transition and charge transfer of transitional metal ions.The sapphire color depends on the content of Fe2+, Fe3+, Ti4+and Ti3+ in the crystal lattice,as well as the ratio of Fe2+ / Ti4+and Fe3+ / Fe2+.
