摘要
采用喷雾热解法制备了球形SrMoO4∶Eu3+荧光粉。研究了温度对SrMoO4∶Eu3+荧光粉体的晶相结构、显微形貌及发光性能的影响。结果表明,不同温度下得到的粉体都具有纯的SrMoO4晶相;300℃下喷雾制得的钼酸锶粉体颗粒部分具有空心球形结构,在400、500和600℃下喷雾制得的钼酸锶粉体颗粒呈现实心球形结构;温度为500℃时所得样品发光强度最强。
Spherical SrMoO4∶Eu3+ phosphor was prepared by spray pyrolysis.The influences of temperature on phase composition,microscopic morphology and fluorescent performances of the SrMoO4∶Eu3+ phosphor were investigated.The results indicated that pure SrMoO4 phase could be obtained at different temperatures.Part of SrMoO4 particles prepared at 300℃ by spray pyrolysis had hollow spherical structure,and SrMoO4 particles with solid spherical structure were prepared above 300℃ by spray pyrolysis.The emission intensity of the SrMoO4∶Eu3+ phosphor prepared at 500℃ was the strongest.
