The VUV-UV spectroscopic properties of Ce3+ in Ba2Mg(BO3)2,Ba2Ca(BO3)2 and Sr2Mg(BO3)2 were compared,and the relation between the energy of the 4f→5d transition of Ce3+ and the coordination environments of substituted alkaline earth ions was discussed.The chromaticity coordinates of Ce3+ activated X2Z(BO3)2(X=Ba,Sr;Z=Ca,Mg) phosphors were changeable from blue to whitish and further to green range by varying the doping concentration of Ce3+ or the types of substituted alkaline earth ions upon 172 nm excitation. 相似文献
