摘　　要：合成了细颗粒灯用绿色荧光粉;对各稀土离子分别进行光谱和发光性能研究,发现Ce3+、Tb3+、Gd3+离子的浓度对荧光粉的亮度有较大影响;该粉主发射峰是545nm,发光亮度高;颗粒较细且粒度分布均匀,平均粒径为3μm～4μm。The small-sized green-emitting phosphors is synthesized The spectra and luminescence properties of all the rare-earth ions are studied,respectively It has been found that the concentrations of Ce3+,Tb3+ and Gd3+ ions have a great effect on luminosity of the phosphors The maximum emitting wavelength is 545 nm and its emission luminosity is high; the particle size is small and its distribution is even; the average particle size is 34μm
