（Ca_（1－A）La_xCe_yMn_z）B_4O_7系列荧光材料的合成及其稳

Synthsis of Fluorescence Material of the Serise of(Ca1-ALaxCeyMnz)B4O7 and Study of Its Stability

为了寻找高效荧光材料，采取高温固相弱还原方法合成了（Ｃａ１－ＡＬａｘＣｅｙＭｎｚ）Ｂ４Ｏ７的系列荧光体（０．５≤Ａ＝ｘ＋ｙ＋ｚ＜１），其在２５４ｎｍ紫外光激发下发黄绿光．作者研究了Ｃｅ３＋、Ｍｎ２＋浓度对其发光亮度的影响，并对其稳定性进行了探讨．

in order to find out effident luminesent materals,the sense of(Ca1-ALaxCeyMnz)B4O7was synthsed by means of high-temperature and weak-reduCtion ill solid phase.It gives yellow-green light under the excitation of 254nm UV light. It was studied that the concentration ofCe3+.Mn2+ influnces luminous intensity. The stability of the luminesed laterals was also studied.
