Аннотация: Luminescence thermometry, leveraging the temperature-dependent luminescent properties of coordination compounds, offers precise and remote temperature measurement. However, many existing luminescent thermometers exhibit a narrow peak in temperature sensitivity, restricting their effective operating range. In this study, we synthesized new complexes [LnL2(NO3)(TPPO)2], where Ln = Eu (1), Tb (2), Gd (3), Tb0.94Eu0.06 (4), (HL - 4,4,4-trifluoro-1-(furan-2-yl) butan-1,3-dione, TPPO - triphenylphosphine oxide, which demonstrate an exceptionally wide and stable range of maximum temperature sensitivity of 3 %×K−1, spanning from 180 to 320 K. Furthermore, the temperature uncertainty remained low and stable across the same temperature region, ensuring reliable measurements. An unusual behavior was observed in the ion-to-ion energy transfer process rate constant, which exhibited an additional peak between 120 and 180 K. This phenomenon warrants further investigation to fully understand the underlying mechanisms. The obtained results allow for creation of new highly efficient luminescent thermometers tailored for specific complex applications, including cryobiology and microfluidics.
