采用水热蒸发法制备了KCl∶Ce3＋荧光粉。测量并分析了材料在室温下的真空紫外激发光谱及相应的发射光谱。结果表明激发谱显示6个峰,峰位分别为149、194、206、219、233和251nm。其中149nm的激发峰是基质吸收引起的;194、206、219、233和251nm是Ce3＋离子的4f→5d跃迁引起的。发射峰显示双峰结构,峰位分别是311和326nm。此峰对应于Ce3＋离子的5d→4f（2F5/2,2F7/2）跃迁。

A seres KCl： Ce3＋ of phospors were prepared by hydrothermal approach. The VUV excitation and emission spectra were measured at room temperature. The excitation spectra contain two broad band at 149 and 251nm. The peak at 149nm can be attribute to the host related absorption and that at 194,206,219,233,251nm is due to the 4f→5d transitions of Ce3＋. Two emission peaks at about 311 and 326nm were obsereved and they were ascribed to 5d →4f（2 F5/2,2 F7/2 ） transitions of.
