The PL spectrum excited with the 210 nm of a Xe lamp at room temperature revealed a strong green emission band centered at about 500 nm with FWHM about 90 nm and a weaker near UV emission band centered at about 380 nm with FWHM about 15 nm.

• 用He-Cd激光器的325 nm激光对四脚状样品进行发射光谱分析,发现其近紫外激子发光大大增强而绿色缺陷发光相对较弱,近紫外的峰值位于383 nm,半峰全宽约为16 nm;
