摘要
用高温固相法合成了以六硼酸镉为基质 ,Mn2 +为激活剂的光致发光材料 .对样品进行的荧光光谱分析结果表明 ,此发光材料的主激发峰位于 368nm ,来自Mn2 +的6A1 - 4 E( 4 D)跃迁吸收 ,主发射峰位于 62 0nm ,来自Mn2 +的4T1 ( 4 G) - 6A1 ( 6S)跃迁发射 .同时对样品进行了X衍射测试 ,并用扫描电镜观察了晶体外貌 .
We have synthesized the material of red photoluminescence by spread methods of high temperature and solid of in Cd 2B 6O 11 :Mn. Analysis of fluorescence spectrum shows, the excitation band of Mn 2+ peaking at 368?nm are due to 6 A 1- 4E( 4D) transition, emission band peaking at 620?nm are due to 4 T 1( 4G)- 6A 1( 6S) transition. Structural properties were investigated by XRD, crystallinity were investigated by SEM.
