| 摘 要： | 本文较详细地分析论述了山东昌乐蓝宝石EPR谱各共振吸收带的位置、强度及其随EAC轴角度变化规律等特征，对各吸收带的归属也进行了深入讨论。通过EPR谱分析，笔者认为山东昌乐蓝宝石中Fe3 是大量存在的，并有可能是Fe的主要存在形式，由此指出，在昌乐蓝宝石改色工艺中过于看重将Fe2 转变为Fe3 将导致蓝宝石灰色成分增加。

| Abstract: | The EPR spectra of natural sapphires from Changle,Shandong are reported in this paper.The position and intensity-changing and formation of each absorption band are discussed in detail-The hue of sapphires is due to Fe2 /Ti4 charge transfer so that much research has been done onFe2 than Fe3 . It is mostly accepted that most of the Fe ions are present as Fe' , but the EPRsPectra show that Fe3 may be the main form of the total Fe in the sapphires. This conclusion canhelp us to choose a better enhancement for the sapphires from Changle, Shandong. |
