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-xLuxCe0.06)(ScMg)Si3O12(缩写为CLSMS∶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。通过控制Lu的摩尔分数可以获得纯的晶相，进一步实现Ce3+的高强度宽带发射。当Lu的摩尔分数x=0.54时，样品的荧光强度达到最大值，其值为不含Lu时荧光强度的156%。同时，含Lu的荧光粉比不含Lu的荧光粉表现出优越的温度特性。将含有Lu的荧光粉和蓝光LED芯片结合，得到显色指数86，流明效率为86 lm/W的白光LED。

Lu modified (Ca2.94-xLuxCe0.06)(ScMg)Si3O12 (CLSMS∶Ce3+) 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 Ce3+ rather than the internal quantum efficiency. Intense and broadband emission is realized by controlling the Lu content to obtain a pure CLSMS crystal phase. The maximum luminescence intensity is obtained at x=0.54, which is as high as 156% of the Lu free phosphor. Combining the present phosphor with a blue LED chip, a white LED with an excellent color rendering index of 86 and high luminous efficiency of 86 lm·W-1 is obtained.
