Second-Coordination-Sphere Cation Substitution as a Tool for Controlling Phase Transitions and Performance of the Luminescence Thermometry
Muhammad T. Abbas, M. Szymczak, M. Fandzloch +3
Despite the exceptionally high relative sensitivities achieved by luminescent thermometers based on first-order structural phase transitions, their principal limitation lies in the…
Dual-Mode Luminescent Thermometry in LiYO2:Nd3+,Yb3+ Enabled by Structural Phase Transition and Phonon-Assisted Energy Transfer
M. Tahir Abbas, M. Szymczak, D. Szymanski +3
In this work, a dual-mode luminescent thermometer operating via both ratiometric and lifetime-based readout strategies was developed, enabled by the coexistence of two thermally dr…
Phase Transition Under Control: Toward Application-Oriented Luminescence Thermometry and Thermally Activated Emission
M. T. Abbas, M. Szymczak, D. Szymanski +4
Phase-transition-based luminescent thermometers are characterized by two inherent limitations: a narrow thermal operating range and the presence of a hysteresis loop in the thermom…
Breaking Sensitivity Barriers in Luminescence Thermometry: Synergy Between Structural Phase Transition and Luminescence Thermal Quenching
M. Tahir Abbas, M. Szymczak, M. Drozd +4
One of the key parameters determining the performance of a luminescent thermometer is its relative sensitivity. In ratiometric luminescence thermometry, high relative sensitivity t…
Expanding the Horizons of Phase Transition-Based Luminescence Thermometry
M. Tahir Abbas, M. Szymczak, V. Kinzhybalo +3
The limited operational range of phase transition-based luminescence thermometers necessitates the exploration of new host materials exhibiting first-order structural phase transit…
NIR-to-NIR lifetime based thermometry with the thermally elongated luminescence kinetics driven by structural phase transition in LiYO2:Yb3+
M. T. Abbas, M. Szymczak, V. Kinzhybalo +2
Among the various techniques used in luminescence thermometry, luminescence kinetics is considered the least sensitive to perturbations related to the optical properties of the med…
