摘要

采用水热法合成了系列NaGd(MoO₄)₂∶Er³⁺,Yb³⁺上转换发光粉。利用X射线衍射仪、扫描电子显微镜和上转换发光光谱仪等对样品的结构、形貌和发光性能进行表征。结果显示,合成的样品均具有四方晶系NaGd(MoO₄)₂结构;pH对样品的形貌有影响;980nm红外光激发下,NaGd(MoO₄)₂∶Er³⁺,Yb³⁺上转换发光粉显示来自于Er³⁺的 ²H_11/2→⁴I₁₅和 ⁴S_3/2→⁴I_15/2跃迁产生的绿光发射和 ⁴I_9/2→⁴I_15/2跃迁产生的红光发射。比较各样品的发光强度和绿光/红光相对积分强度比,结果显示上转换发光强度和绿光/红光相对积分强度比与晶粒尺寸、晶粒表面形貌,以及Er³⁺和Yb³⁺掺杂浓度有关。讨论了可能的上转换发光过程,并计算了样品的色坐标。

Abstract

A series of NaGd(MoO₄)₂∶Er³⁺,Yb³⁺ upconversion phosphors were synthesized by hydrothermal method.The structure,morphology and upconversion luminescence properties were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM) and upconversion luminescence spectrofluorometer.The results showed that all the synthesized samples had tetragonal NaGd(MoO₄)₂ structure.The pH value had an effect on the morphology of the sample.NaGd(MoO₄)₂∶Er³⁺,Yb³⁺ upconversion phosphors under 980nm infrared excitation showed green emission from ²H_11/2→⁴I₁₅ and ⁴S_3/2→⁴I₁₅ transition and red emission from ⁴I_9/2→⁴I₁₅ transition of Er³⁺,respectively.The intensity and the integral intensity ratios of green to red emission of the samples were analyzed.The results indicated that the upconversion luminescence intensity and green/red light ratio were related to the grain size,grain surface morphology,Er³⁺ and Yb³⁺ doping concentrations.The possible upconversion luminescence processes were discussed,and the color coordinates of the samples were calculated.
