| 摘 要： | 以Gd2O3和Dy2O3为反应物，共沉淀合成了镝掺杂氧化钆纳米粉体．研究了Gd2O3：D6^3＋的光致发光性质随着Dy^3＋掺杂浓度和煅烧温度的变化关系．通过对荧光强度与激活离子Dy^3＋离子浓度的关系研究发现，Dy^3＋在纳米Gd2O3基质中存在浓度猝灭现象，最佳掺杂浓度为0．7％．

| Abstract: | The nanocrystalline Gd2O3 doped with Dy3+ are synthesized by coprecipitation method,with the Gd2O3 and Dy2O3 are the reactants.The photoluminescence properties of the concentration-dependence and temperature-dependence of the Gd2O3:Dy3+ nanocrystallines have been investigated.The concentration quenching phenomenon of Dy3+ in Gd2O3 was observed.The optimism doping concentration is 0.7%. |
