摘要
采用溶胶凝胶法制备Li^+、Li^+-Mg^2+共掺杂的YBO3:Eu3+薄膜。研究了Li^+及Li^+-Mg^2+掺杂条件下Eu^3+激发的Y BO3荧光材料的物相结构、微观形貌,及掺杂后对薄膜产生的光致发光特性的影响。结果表明:于YBO3:Eu^3+薄膜中掺杂Li^+,Li^+会改变YBO3晶体场环境,其发光强亦能有明显的提高,最大能提高近17%,当Li^+掺杂量不变,同时掺入Mg^2+时,其发光强会出现进一步提高,最大能提高近20%。
The fluorescence thin films of YBO3:Eu^3+ with Li^+ doping and Li^+-Mg^2+ co-doping were prepared by solgel method.The microstructure and phase structure of YBO3∶Eu^3+ fluorescent materials doped with different ions were studied.The results s how that when doping Li^+ in YBO3:Eu^3+ thin film,Li+will change the crystal field,and the luminescence intensity can also be increased,the maximum to around 17%.When codoping Li^+ and Mg^2+,the luminescence intensity will be further increased,with the maximum to around 20%.
