The result of TEM revealed that the average size of the single phase Y2O2S:Eu3+ was 30 nm,which was according with the result calculated by Debye-Scherre formula,luminescent spectra of Y2O2S:Eu3+ were also analysed in this paper.

• 透射电子显微镜(TEM)扫描结果显示纳米材料的平均颗粒尺寸为30 nm,与Debye-Scherre公式计算的结果基本一致。 荧光光谱中,激发光谱分为3个区域,200-280 nm的区域为Y2O2S基质的激子激发带,峰值为262 nm;
