Although the considerable potential of luminescence thermometry based on emission kinetics has been widely demonstrated, reliable tools for the intentional prediction of thermometr…
Visual Luminescence Thermometry Enabled by Phase-Transition-Activated Cross Relaxation of Tb3+ Ions
L. Marciniak, M. Szymczak
The development of visual luminescent thermometers capable of exhibiting pronounced color changes in response to temperature variations requires the rational design of phosphors wi…
Unusual Thermally Induced Blueshift and Emission Amplification of Mn2+ ions Enable Filter-Free Luminescent Thermal Imaging
Y. Abe, M. Szymczak, J. Zeler +1
The shift from point-based thermal sensing to filter-free thermal imaging requires luminescent thermometers that exhibit pronounced and thermally driven spectral changes within spe…
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…
