采用微波辅助凝胶燃烧法制备了Ca2MgSi2O7∶Eu3+红色荧光粉,运用XRD、荧光分光光度计等对合成样品进行分析表征,并探讨了焙烧温度、助熔剂用量、Eu3+浓度等对样品发光性能的影响.结果表明:所得样品为四方晶系的Ca2MgSi2O7晶体结构.Ca2MgSi2O7∶Eu3+的激发光谱由一宽带和一组锐线峰组成,分别归属于Eu3+-O2-之间的电荷迁移态和Eu3+的f→f跃迁.样品的发射光谱主要由两个强发射峰组成,分别位于591 nm和619 nm处,属于Eu3+的5 D0→F1磁偶极跃迁和5D0→7F2的电偶极跃迁.研究发现:当焙烧温度为1000℃、助熔剂H3BO3用量为15％时,样品发光性能较好；Eu3+浓度(x)对样品Ca2-xMgSi2O7∶Eu3x+的发光强度影响较大,当Eu3+浓度x在0.02 ～0.16范围内变化时,随着Eu3+浓度的增加,样品的发光强度不断增加,未出现明显的浓度猝灭现象.
