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。

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.
