AB  - Luminescence thermometry uses temperature-dependent emission of light for remote sensing. Dy3+ is established as a perspective ion for high-temperature probes, but given that there is an infinite number of potential hosts it is impossible to find conventionally the one with the best performance. Judd-Ofelt thermometric model can predict sensitivities but it was not yet experimentally validated on Dy3+ ion. Pure phase CaYAlO4:Dy3+ powder was synthesized via the modified Pechini method. Photoluminescence spectra were taken from 300 to 600 K. Luminescence intensity ratio was estimated using 4 I15/2 and 4 F9/2 levels. Experimentally obtained thermometric parameters and sensitivities showed an excellent matching with those obtained from the Judd-Ofelt, indicating the potential application of the Judd-Ofelt model for fast assessment of Dy3+-doped luminescent sensor thermometric perspective. The maximum absolute and relative sensitivities are ~0.001 K− 1 at 600 K and ~1.4% K− 1 at 300 K, respectively. The optimum temperature range for the CaYAlO4:Dy3+ probe is from 370 to 616 K.

AB  - Energy level positions, refractive index values, Judd–Ofelt (JO) intensity parameters, Slater integrals, and spin-orbit coupling parameters are taken from the literature for 27 Dy3+-doped materials (five crystals and 22 glasses). Investigated are only the transitions that are used for the Boltzmann-type luminescence intensity ratio (LIR) thermometers (transitions from the three thermalized levels, 4F9/2, 4I15/2, and 4G11/2 to the ground level). Reduced matrix elements of these three transitions are calculated from the Slater integrals and spin-orbit coupling parameters and they are compared to the most frequently used values from Carnall's tables. The comparison of JO parameters shows the smaller variation of the Ω6, related to rigidity, in crystal hosts than in glasses, and the opposite was observed for the Ω2,4 parameters. LIR performances are simulated by the JO thermometric model for each material by the conventional LIR and the LIR that exploits the third thermalized level. The comparison of the predicted figures of merit in luminescence thermometry reveals the most promising thermometric Dy3+ doped crystals and glasses. © 2022 Wiley-VCH GmbH
