摘要：
The up-conversion luminescent material KYb2F7∶2% Er3+ was synthesized using the hydrothermal method. The synthesized sample was confirmed to be pure phase with an orthorhombic morphology by X-ray diffraction and scanning electron microscopy. Under 980 nm laser excitation，the sample exhibited two green emission peaks at 527 nm and 543 nm，as well as a dominant red emission peak at 655 nm. The temperature-dependent upconversion （UC）emission spectra showed that the emission intensity at 545 nm and 655 nm exhibited thermal quenching with increasing temperature. Based on the mechanism of thermal coupling temperature measurement，the temperature sensing performance of 2H11/2→4I11/2 and 4S3/2→4I11/2 thermal coupling energy levels of Er3+ was studied，and the luminous intensity ratio（LIR），absolute sensitivity（Sa），relative sensitivity（Sr），temperature uncertainty（δT），and repeatability（R）of the luminous thermometer were calculated. The maximum relative sensitivity was 0. 99%·K−1 at 313 K，the minimum temperature uncertainty was 0. 73 K at 313 K，and the repeatability exceeded 99%，ensuring the reliability of the thermometer. All the experimental results indicate that KYb2F7∶2% Er3+ has potential application value in temperature sensing. © 2024 Editorial Office of Chinese Optics. All rights reserved.
