AB  - Luminescence thermometry exploiting luminescence kinetics as a thermometric parameter is regarded as one of the most reliable temperature readout techniques. Transition metal ions are of particular interest in this application which is due to the possibility of modulating their spectroscopic properties by changing the strength of the crystal field of the matrix. In this work, we present a strategy to modulate the thermometric parameters including the relative sensitivity and useful temperature range of luminescent thermometers based on the lifetime of Ti3+ ions by introducing lanthanide (Ln3+) doping in SrTiO3 and CaTiO3. The mutual effect of the distortion of the local symmetry of the Ti3+ ions associated with the introduction of Ln3+ ions and/or the Ti3+ → Ln3+ energy transfer enabled relative sensitivities of SR = 5.87% K−1 at 140 K for SrTiO3:Dy3+ and SR = 4.51% K−1 at 251 K for CaTiO3:Gd3+. © 2022 The Author(s)

AB  - The co-doping of SrTiO3:Mn4+ luminescent nanocrystals with trivalent lanthanide ions (Ln3+ = Lu3+, Tm3+, Er3+, Ho3+, Dy3+, Eu3+, and La3+) is demonstrated as a new strategy for significant sensitivity improvement of lifetime-based luminescent thermometers. SrTiO3:Mn4+:Ln3+ nanocrystals of about 25 nm diameter were prepared by the modified Pechini method and characterized using X-ray powder diffraction and electron microscopy techniques. The temperature dependence of Mn4+ emission in SrTiO3 was considerably altered by the co-doping of Ln3+ due to the cooperating effects of Mn4+ → Ti3+ and Mn4+ → Ln3+ energy transfers. A substantial enhancement of the relative sensitivity of lifetime-based thermometry as high as 145% with respect to the unco-doped nanocrystals reveals the success of the approach. The obtained values of maximal relative sensitivity for different Ln3+ co-dopants are 5.10% K−1 at 290 K for Er3+, 5.00% K−1 at 301 K for Eu3+, 4.84% K−1 at 303 K for Dy3+, 4.71% K−1 at 289 K for Ho3+, and 3.87% K−1 at 290.7 K for Lu3+.
