摘要：

In this work，a novel Yb3+ and Ho3+ co-doped Ba3In（PO4）3 up-conversion phosphor was synthesized by high temperature solid-state method，and its crystal structure，up-conversion luminescence and energy transfer mech⁃ anism were studied. Under 980 nm laser excitation，Yb3+ absorbs energy and transfers to Ho3+. In addition，the laser power has no significant effect on the luminescent color of the phosphor，and the luminescent color is mainly concen⁃ trated in the orange-red region（0. 543，0. 452）. The fluorescence lifetime of 0. 05Yb3+ and 0. 032Ho3+ doped phos⁃ phor is about 467. 61 μs. The temperature-dependent photoluminescence emission spectra of the phosphor were also measured，and the absolute sensitivity（Sa）and relative sensitivity（Sr）were calculated. The results show that the phosphor has good thermal stability，and the emission intensity at 423 K remains about 81. 68% of that at room tem⁃ perature. The ΔE of 5S2，5F4→5I8，5F5→5I8 transitions are 0. 19 eV and 0. 27 eV，respectively. In addition，the maxi⁃ mum Sa and Sr are 0. 31%·K-1 and 0. 09%·K-1（573 K），respectively. © 2023 Chines Academy of Sciences. All rights reserved.
