Abstract

Yb³⁺/Er³⁺/Tm³⁺ triply doped LuF₃ mesocrystals have been successfully synthesized to explore their possible application in optical temperature sensors. Especially, owing to the non-resonant energy match between the ⁴F_9/2 (Er³⁺) and ³F₂ (Tm³⁺) states and thus the occurrence of multiphonon assisted energy transfer process (Er³⁺→ Tm³⁺), two upconversion (UC) emission bands corresponding to F_9/24→ I_15/24 (Er³⁺) transition and F₂3 → H₆3 (Tm³⁺) one exhibit distinct temperature-dependent behaviors, which result in monotonous decrease of the related fluorescent intensity ratio (I_Er/I_Tm) with increased temperature. Consequently, the high sensitivity of 20.6% per K for LuF₃:Yb³⁺/Er³⁺/Tm³⁺ mesocrystals may make them very promising candidate as optical temperature sensor.
