Abstract To develop multi‐mode fluorescence thermometer with high performance, Lu 2 WO 6 :Er 3+ ,Yb materials were successfully designed and prepared. Under 980 nm excitation, the material can achieve accurate temperature measurement under three models. The above models are based on different parameters, including two FIR (fluorescence intensity ratio) derived from thermally coupled energy levels (TCELs) ( H 11/2 / 4 S 3/2 ) non‐thermally (NTCELs) F 9/2 ), as well lifetime (FL) monitoring of level transition to ground state. In mode TCELs, maximum relative sensitivity R‐max minimum resolution 1.261 %K –1 0.237 K, respectively. repeatability five‐cycle measurements is 98.5%. value FL reach 0.862 0.201 −1 , obtained outcomes suggest that might be considered promising candidates for three‐mode thermometry.
