Abstract
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.
