摘　　要：利用固相反应法制备了Zn^(2+)-Er^(3+)-Yb^(3+)共掺的Y2O3红色上转换荧光粉,研究了Zn^(2+)的掺杂量对上转换发光性质的影响.结果表明,上转换荧光强度随着Zn^(2+)掺杂量增加而增加.Zn^(2+)掺杂量为12%的样品的红光强度比无Zn^(2+)掺入的样品红光强度提高14倍.通过对光谱的分析,解释了上转换发光机理,并对上转换发光增强的原因进行了讨论.Zn2 ＋-Er3 ＋-Yb3 ＋ codoped Y2O3 red upconversion phosphor powder was prepared by solid reaction process, and the dependence of upeonversion luminescence properties of the samples on Zn2＋ doping concentration was investigated. The results indicated that the upconversion luminescence of the samples enhanced with increase of Zn2＋doping concentration. Compared to the non-Zn2＋-doped sample, the red luminescence intensity of the sample corresponding to 12% Zn2＋ doping concentration increases by 14 times. By investigation on the spectra,the upconversion mechanism was explained, and the luminescence enhancement reason was explored.
