本文报道了用离子(Be~(2+)和Ti~(4+))注入技术优化处理山东蓝宝石的工作.对处理前后样品一系列测试和实验的结果表明:(1)样品经过离子注入处理后,表面光泽明显增强,表面光洁度保持良好;(2)山东蓝宝石注入Be~(2+)后,颜色较处理前更深,说明Be~(2+)虽然不是致色离子,但可对蓝宝石颜色产生明显的影响;(3)注入Ti~(4+)后,山东蓝宝石的颜色变浅变艳了.进一步证明了山东蓝宝石的颜色深是由于Fe~(2+)浓度高,同时Ti~(4+)浓度相对太低所致,对今后山东蓝宝石乃至其它宝石的优化处理提供了新的思路和方法.
The paper reports the technique using ion implantation(Be~(2+) and Ti~(4+))technique in the Shandong sapphire treatment. Some testing and research had been done before and after the implantation. The results show that : (1)As ion was implanted in, the luster turned obviously brighter. While surface of the samples kept smooth as well as before;(2)As Be~(2+) was implanted in Shandong sapphire, the color turned obviously heavier, though Be~(2+) was not color-causing element, it could affect the color;(3)As Ti~(4+) was implanted in, the color of Shandong sapphire turned fade and brighter, which indicated that the dark color was because of high proportion of Fe~(2+)while low proportion of Ti~(4+). It is a new method of optimization and treatment in Shandong sapphire and other gems.
