abstract |
In this study, it is shown how the temperature range of luminescent thermometers can be widened in an unprecedented way by combining the intra- and interconfigurational transitions of the Pr3+ ion in a single material. Using Sr2GeO4:Pr3+ crystalline powders as an illustrative example, the implementation of luminescence thermometry is reported in the broadest temperature range up to now (17-600 K) with a remarkable performance: maximum relative sensitivity values of 9.0%.K-1 (at 22 K, cryogenic range), 0.6%.K-1 (at 300 K, physiological range), and 0.5%.K-1 (at 600 K, high-temperature range) and minimum temperature uncertainty of 0.1 K. |
