摘要	Hexagonal phase NaYF4∶20%Yb，2%Er@NaYF4@NaYbF4∶0.5%Tm@NaYF4 lanthanide-doped nano⁃particles with the core@multishell structure were synthesized by solvothermal method. The upconversion luminescence （UCL） properties of the materials at temperature from 10 K to 295 K were studied under 980 nm excitation. Green and red UCL from Er3+ and blue UCL from Tm3+ were observed in the visible light range. The luminescence intensity of green UCL first increased and then decreased， while the luminescence intensity of blue light showed a thermal attenuation trend with the temperature increase. The method of temperature-dependent luminescence intensity ratio （LIR） can be used in accurate temperature measurement， and the relative sensitivity is up to 3.2%·K-1. With various thicknesses of the outer luminescent shell， the different tendencies of LIR can be realized， which can be applied to cryogenic field anticounterfeiting. © 2023 Chines Academy of Sciences.
