摘　　要：采用高温固相法制备PDP绿色荧光粉Zn2SiO4:Mn2+,研究了Zn/Si摩尔比、激活剂Mn2+含量的变化对荧光粉真空紫外光谱、相对亮度、余辉时间及色坐标的影响.试验结果表明,当Zn/Si摩尔比为1.905,Mn2+含量为0.11 mol时,所制备的荧光粉Zn2SiO4:Mn2+的色坐标x=0.2109,y=0.7115,发射波长525 nm,余辉时间t1/10为3.5 ms.Green emitting phosphor Zn2SiO4 .Mn^2＋ for PDP was synthesized by high temperature solid state method. The effects of the Zn/Si ratio and Mn^2＋ content on the VUV spectra, relative brightness, afterglow time and chromaticity coordinate of Zn2SiO4 ：Mn^2＋ were studied. When Zn/Si ratio and Mn^2＋ content of the phosphor was 1.905 and 0.11, the chromaticity coordinate was x=0. 2109,y=0. 7115, the emission wavelength and afterglow time of the phosphor was 525 nm and 3.5 ms, respectively.
