| Abstract: | The Ca2MgSi2O7：Eu2＋ green phosphor was synthesized by chemical coprecipitation.The result showed the excitation spectrum of the Ca2MgSi2O7：Eu2＋ green phosphor extended from 300 nm to 480 nm,and the peaks appeared around 310 nm and 385 nm,thus the phosphor can be excited effectively by InGaN chip in the range of 360~480 nm.The peak of the emission spectrum appeared around 512 nm.The strongest emission intensity was obtained when Eu2＋doping concentration reached 3 ﹪. |
