Up-Conversion Luminescence and Temperature Sensing of Er³⁺/Yb³⁺ Codoped Y_2(1-x %)Lu_2x %O₃ Solid Solution.

ABSTRACT: In this paper, Er³⁺/Yb³⁺ codoped Y_2(1-x%)Lu_2x %O₃ solid solution was prepared through the sol-gel method, and the substitution of Y³⁺ by Lu³⁺ ions in Y₂O₃ was confirmed by X-ray diffraction data. The up-conversion emissions of samples under 980 nm excitation and the relative up-conversion processes are investigated. The emission shapes do not vary with the change in doping concentration due to the unaltered cubic phase. The red-to-green ratio changes from 2.7 to 7.8 and then declines to 4.4 as the doping concentration of Lu³⁺ increases from 0 to 100. The emission lifetimes of green and red have similar variation: the emission lifetime decreases with doping concentrati
