摘要:
不同稀土离子掺杂氧化锡薄膜展现出迥异的敏化发光性能，因此探究氧化锡(SnO2)与稀土离子之间的能量传递过程对制备宽光谱发光薄膜具有重要意义。通过溶液旋涂法，利用二水合氯化亚锡、六水合氯化铽以及六水合氯化铕制备出铽、铕共掺氧化锡(SnO2:1% Eu3+/x% Tb3+(x =0,0.1,0.5,1.0))薄膜，并通过X射线衍射(XRD)、扫描电子显微镜(SEM)、紫外-可见吸收光谱(UV-Vis)、光致发光谱(PL)、光致发光激发谱(PLE)、时间分辨光致发光衰减谱(TRPL)等对薄膜的结构形貌和光学性能进行表征。结果表明：单纯铕离子(Eu3+)掺杂的SnO  2薄膜敏化发光性能不佳，通过共掺杂铽离子(Tb3+)可以实现能量的阶梯传递，提高Eu3+离子的敏化发光强度；随着Tb3+离子掺杂浓度的提高，Eu3+离子的发光呈现出先增强后减弱的趋势，Tb3+离子的浓度为0.5 at.%时Eu3+离子的发光性能最好，比未共掺杂的样品高约3倍。该研究本文结果为制备高效的稀土掺杂氧化锡发光材料提供了新的思路。
