摘要
利用金属硝酸盐和尿素发生的氧化还原反应,制备了绿色长余辉发光粉SrAl2O4:Eu,Dy,反应在600℃下完成。用X射线衍射分析、扫描电镜、发射光谱、粒度分布等多种测试手段对燃烧合成法的产物的性质进行了研究。
The aluminate phosphor SrAI2O4 ：Eu, Dy has been synthesized by the combustion on mixture of respective metal nitrates and urea. The process is energy-saving, instantaneous and safe. The reaction can be completed at 600℃ furnace temperature, which is much lower than that used in traditional solidi sate reaction process. The phosphor was characterized by XRD , SEM, fluorescence spectra and particle size distribution.
