摘要
通过对SiO2:Nd的PL谱分析,并与SiO2:La、SiO2:Ce、Si+→SiO2、C+→SiO2等的PL谱进行比较,总结出薄膜光致发光的一些特性.
Through the analysis of the photoluminescence spectra for sample SiO2:Nd and the comparison of the photoluminescence spectra for the samples SiO2: La, SiO2: Ce, Si+SiO2 and C+SiO2, the article summarize some photoluminescence properties of impurity—doped Si—based oxide films.
