摘要

氟氧化物兼有氧化物优异的稳定性和氟化物的低声子能量，是上转换发光材料的一种热点基质材料，因而研究六方相LaOF：Er，Yb的上转换发光性能及其温度特性具有重要意义。本文采用水热法制备了六方相LaOF：Er，Yb荧光材料，通过X射线衍射（XRD）、扫描电镜（SEM）和荧光光谱对其结构和上转换荧光性能进行表征。实验结果表明，水热法120 ℃得到六方相LaF,3,，经800 ℃和1 000 ℃退火后分别形成四方相LaOF和六方相LaOF。980 nm激发下，六方相LaOF：Er，Yb中Yb,3+,与Er,3+,存在能量传递，通过双光子吸收产生绿光和红光的上转换荧光，并且Yb,3+,与Er,3+,的最佳浓度分别为3%和1%。最后研究了六方相LaOF：Er，Yb在温度传感方面的应用，其在150~400 K温度范围的相对灵敏度和绝对灵敏度分别为0.037 K,-1,和0.004 3 K,-1,。该材料具有优异的温度传感特性，对荧光温度传感器件的设计和应用具有指导意义。

Abstract

Recent years, Up-conversion(UC) luminescence exhibits potential application in temperature measurement based on FIR(fluorescence intensity ratio) technique, which has drawn considerable attention. Lanthanum oxyfluoride(LaOF) inherits the advantage of low lattice phonon energy, and exhibits superior thermal and chemical stability, showing efficient UC luminescence. Thus, limited attention has been paid to the temperature sensing characteristics of Er,3+,/Yb,3+, co-doped LaOF. In the present work, rhombohedral LaOF:Er, Yb phosphors are prepared using hydrothermal method. The structure and fluorescence properties are characterized by X-ray diffraction, SEM and fluorescence spectra. Hexagonal LaF,3, is prepared using hydrothermal method at 120℃. After annealing at 1 000℃, rhombohedral LaOF is obtained. The agglomerated particle crystallizes into one larger particle in the range of several micron following annealing. Excited by 980 nm, the characteristic emission from the Er,3+, ion is observed, including two green emission bands and one red emission,2,H,11/2,→,4,I,15/2, and ,4,S,3/2,→,4,I,15/2, as well as ,4,F,9/2,→,4,I,15/2, transitions. Energy transfer between Er,3+, and Yb,3+, is confirmed because of two-photon process, resulting in upconversion emissions. Finally, the optical temperature sensing properties of R-LaOF:Yb, Er are investigated. The results suggest that R-LaOF:Er, Yb exhibits intense emission and high sensitivity. Its maximum relative sensitivity ,S,R, and absolute sensitivity,S,A, are 0.037 K,-1,and 0.004 3 K,-1, respectively in the temperature range of 150-400 K, suggesting it is a potential candidate in temperature sensing.
