| 摘 要： | 利用高温固相反应制备了一种由Lu改进的黄色荧光粉(Ca2.94-x LuxCe0.06)(ScMg)Si3O12(缩写为CKSMS:Ce3+),其中,0≤x≤0.94.同时研究了Lu含量对荧光粉的晶相、发光性质以及温度特性的影响.结果表明,Lu的引入导致荧光增强,其原因是由于Ce3+吸收增强而不是荧光粉内量子效率增加....

| Abstract: | Lu modified(Ca_(2.94-x)Lu_xCe_(0.06))(ScMg)Si_3O_(12)(CLSMS:Ce~(3+))yellow emitting phosphors are prepared by solid-state reaction.The effects of Lu content on crystal phase formation,luminescence properties and temperature characteristics are studied.It is revealed that the Lu induced luminescent enhancement can be attributed to the increase of absorbance of Ce~(3+)rather than the internal quantum efficiency.Intense and broadband emission is realized by controlling the Lu content to obtain a pure CLSMS cry... |
