中文摘要：

合成了NaYS2:0.20Yb3+,0.03Er3+和NaYS2:0.03Er3+粉末材料,通过材料的Stocks和Anti-Stocks光谱,研究了Er3+和Yb3+跃迁几率对激发方式的依赖特征,以及局域环境对S2-Re3+(Re3+=Yb3+或Er3+)电荷迁移态的影响,探讨了在共掺杂和单掺杂状态下Yb3+和Er3+间的能量传递和Er3+的Stocks和Anti-Stocks辐射跃迁机制。

英文摘要：

NaYS2:0.20Yb3+,0.03Er3+ and NaYS2∶0.03Er3+ powder samples were synthesized with solid-state reacting methods,respectively.The Stocks and Anti-Stocks light-emitting properties with Er3+ were researched.Dependences of the emission features on excited population processes were exhibited with the spectra obtained following an excitation,respectively,at 980,532 and 408 nm.Effects of local field of doped Re3+(Re3+ standing for Yb3+ or Er3+) on S2-Re3+ charge transfer state(CTS) were observed.Further,the energy-transfer processes between Yb3+ and Er3+ based on the energy matching conditions and the Stocks and Anti-Stocks emission mechanism with Er3+ should be suggested with schematic energy-level schemes.
