%X 用中频磁控溅射方法在SiO2/Si基底上制备了五组固定掺铒浓度不同镱铒浓度比率的镱铒共掺Al2O3薄膜样品.室温下测量了薄膜在1.430μm~1.630μm波段范围内光致发光光谱.研究发现,镱的掺入有效地提高了三价铒离子的光致发光强度,最优的镱铒掺杂为:掺铒0.33 mol%,Yb3 ∶Er3 =10∶1,比相同掺铒浓度单掺铒样品光致发光峰值强度增强40倍;确定的掺铒浓度,有着固定的最佳镱铒浓度比率,主要是镱铒离子间的正向和反向能量传递相互作用的结果,但最佳镱铒浓度比率随着掺铒浓度的增加呈现下降趋势;单掺铒薄膜的光致发光峰值强度随掺铒浓度呈现近Gauss形状变化,而最佳镱铒共掺样品的光致发光峰值强度随掺铒浓度呈现了倒Gauss形状变化.
