Er3+ doped sensitizer-rich SrYbInO4 upconversion phosphors with an orthorhombic structure (Pnma) were synthesized by using a high temperature solid state reaction and their phase structure, site occupation and microstructure have been analyzed. Interestingly, upon the excitation from 980 nm pulsed laser diodes, the SrYbInO4:Er3+ phosphor emitted a nearly pure red emission on account of the 4F9/2 → 4I15/2 transition of Er3+. Additionally, based on the pump power dependence of the upconversion intensity and the schematic diagram of the energy levels, the upconversion mechanism in this system was verified in a two-photon process. The temperature-dependent behaviors of the as-synthesized sample demonstrated the potential for applications in optical thermometry.

掺 Er 3+的富敏化剂SrYbInO 4荧光粉的 纯红色上转换发光和光学测温
利用高温固相反应合成了具有正交晶结构(Pnma)的掺Er 3+的富敏化剂SrYbInO 4上转换荧光粉,并对其相结构,位点占据和微观结构进行了分析。有趣的是,在从980nm的脉冲激光二极管,所述SrYbInO激发4:铒3+磷光体发射是考虑到的几乎纯的红色发射4 ˚F 9/2 → 4我15/2尔过渡3+。另外,基于上转换强度对泵浦功率的依赖性和能级示意图,在双光子过程中验证了该系统中的上转换机制。合成样品的温度依赖性行为证明了其在光学测温中的应用潜力。
