We report on overcoming the sensitivity limit of Boltzmann's thermometers by utilization of seven thermalized Dy3+ excited states in the Lu1.5Y1·5Al5O12 host. Emission spectra recorded from room temperature to 938 K show transitions originating from seven 4F9/2, 4I15/2, 4G11/2, 4I13/2, 4M21/2, 4K17/2, and 4F7/2 excited levels to the 6H15/2 ground state. We introduce the multi-cascade LIR (McLIR) by extending the conventional, two-thermalized level Boltzmann-type LIR to seven thermalized levels. This approach provides higher energy differences between thermalized levels which results in five times larger sensitivity than in the conventional LIR. Considering energy differences between Dy3+ excited states of 1043, 2464, 4331, and 5089 cm−1, the luminescence thermometry with McLIR provided 0.35, 0.84, 1.47, 1.73% K−1 relative sensitivities at 650 K, respectively, in four different LIR combinations. The validity of the McLIR method and the effectiveness of thermalizations between levels is ...confirmed with the good theoretical fit of experimental data.
