| 摘 要： | 采用固相烧结法制备一系列Er3+单掺与Er3+/Yb3+共掺0.96Na0.5Bi0.5TiO3-0.04CaTiO3(NBT-CT∶xEr3+/yYb3+,x=0.002~0.015,y=0.010)无铅压电陶瓷。通过X射线衍射仪和荧光光谱仪分别对样品的物相结构和上转换发光特性进行表征和分析。结果表明,样品的主晶相为NBT晶相。在波长为980 nm的近红外光激发下,Er3+单掺与Er3+/Yb3+共掺NBT-CT陶瓷均呈现强的以绿光为主的Er3+特征上转换发光。在NBT-CT∶xEr3+中,当x=0.010时上转换发光性能最佳;Yb3+能够起到敏化作用,明显增强Er3+的上转换发光强度。

| Abstract: | A series of Er3+ doped and Er3+/Yb3+ co-doped 0.96Na0.5Bi0.5TiO3-0.04CaTiO3(NBT-CT∶xEr3+/yYb3+,x=0.002~0.015, y=0.010) lead-free piezoelectric ceramics were prepared by a solid-state sintering method. The phase structure and up-conversion luminescence properties of the samples were characterized and analyzed by X-ray diffraction and fluorescence spectrofluorometer, respectively. These results show that the main crystal phase of the samples is that of NBT. Under the excitation of a 980 nm near-infrared light, the Er3+ doped and Er3+/Yb3+ co-doped NBT-CT ceramics exhibit characteristic emission of Er3+ with strong dominant green up-conversion emissions. The optimal up-conversion luminescence performance with x=0.010 in NBT-CT∶xEr3+ ceramics are obtained. Yb3+ can act as sensitizer and significantly enhance the up-conversion luminescence intensity of Er3+. |
