摘　　要： 用溶胶燃烧法在1 200℃制备了亚微米级Ca2.40Lu0.54ScMgSi3O12∶0.06Ce3+荧光粉,并对其进行了物相结构、形貌、光致发光性质和热猝灭性质的表征。与传统高温固相法制备的样品相比,溶胶燃烧法不但降低了制备温度,而且制备的Ca2.40Lu0.54ScMgSi3O12∶0.06Ce3+荧光粉的形貌也有所改善。发光性质测试结果表明,亚微米级Ca2.40Lu0.54ScMgSi3O12∶0.06Ce3+荧光粉的发光峰值相比于高温固相法样品有约10 nm的红移,而且样品的热猝灭性质也优于高温固相法样品。 Submicron sized Ca2.40Lu0.54ScMgSi3O12∶ 0.06Ce3+phosphor was prepared by sol-combustion(SC) method.The phase-forming,morphology,photoluminescence and thermal quenching properties of phosphor were investigated.The results confirm that the Ca2.40Lu0.54ScMgSi3O12∶0.06Ce3+phosphor can be prepared by SC method at 1ower temperature,and the morphology is much more uniform than the samples prepared by solid state(SS) method.Photoluminescence measurements show that the emission of the submicron sized Ca2.40Lu0.54ScMgSi3O12∶ 0.06Ce3+phosphor presents a ~ 10 nm red shift compared with the SS sample,and the thermal quenching of the submicron sized Ca2.40Lu0.54ScMgSi3O12∶ 0.06Ce3+phosphor is obviously weaker.
