摘要
利用金属硝酸盐和尿素发生的氧化还原反应，制备了发绿光的铝酸盐发光粉Ｃｅ０．６７Ｔｂ０．３３ＭｇＡｌ１２Ｏ２０．５．反应在６００℃下完成．对产物的性质进行了表征和研究．考察了尿素用量，炉温及其它制备条件对发光粉的性质。
The aluminate phosphor, Ce 0.67 Tb 0.33 MgAl 12 O 20.5 , has been synthesized by the combustion of mixtures 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 solid state reaction process. The phosphor was characterized by XRD, SEM, fluorescence spectra, particle size distribution, density and relative brightness measurements. The effects of different preparation conditions on the properties, especially the brightness, of the phosphor were inspected.
