摘要:
双钙钛矿结构化合物因具有声子能量低、易于稀土离子掺杂、物理化学性质稳定等优势而受到广泛关注。为获得新型温敏上转换材料，通过高温固相法合成了一系列双钙钛矿结构上转换发光材料K3InF6:Er3+,Yb3+。此外，采用X射线粉末衍射仪（XRD）、场发射扫描电镜（FE-SEM）和荧光光谱仪（PL）分别对其成分、结构和发光性能进行了系统表征。结果表明制备的上转换发光材料均为双钙钛矿结构，在980 nm激光激发下，样品可发出明亮的绿光。当Er3+和Yb3+掺杂物质的量的比分别为0.05和0.25时，样品上转换发光强度最大。同时，通过测量变功率的上转换发光光谱,详细讨论了样品中所涉及的上转换发光机理。基于荧光强度比(FIR)技术还研究了样品在303～573 K范围内的温度传感性能，当温度为483 K时，取得的最大绝对灵敏度为9.5×10-3 K-1。所有结果表明，K3InF6:Er3+,Yb3+上转换发光材料具有较高的灵敏度，在温度传感领域具有广阔的应用前景。
Abstract:
Double perovskite compounds have attracted wide attention due to the advantages of low phonon energy, easy doping with rare earth ions, and stable physicochemical properties. To obtain novel temperature-sensitive upconversion materials, a series of up-conversion luminescent materials K3InF6:Er3+,Yb3+ with double perovskite structure were synthesized by hightemperature solid-phase method in this paper. In addition, the composition, structure and luminescence properties were systematically characterized by Xray powder diffractometer (XRD), field emission scanning electron microscope (FE-SEM) and fluorescence spectrometer (PL), respectively. The results show that the prepared up-conversion luminescent materials are all double perovskite structure, and the samples emit bright green light under 980 nm laser excitation, and the up-conversion luminescence intensity of the samples is maximized when the ratio of amounts of Er3+ and Yb3+ are 0.05 and 0.25, respectively. Meanwhile, the up-conversion luminescence mechanism involved in the samples is discussed in detail by measuring the up-conversion luminescence spectra of variable power. The temperature sensing performance of the samples in the range of 303 to 573 K was also investigated based on the fluorescence intensity ratio (FIR) technique, and a maximum absolute sensitivity of 9.5×10-3 K-1 was obtained when the temperature was 483 K. All the results indicate that K3InF6:Er3+,Yb3+ up-conversion luminescent material has high sensitivity and has a promising application in the field of temperature sensing.
