Abstract: 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.
