Ionic-Radius Mismatch as a Structural Lever for Tuning Phase Transitions and Luminescent Thermometry
A. Javaid, M. Szymczak, A. Sieradzki +1
The widespread implementation of luminescence thermometers requires a comprehensive understanding of the structural factors governing their thermometric performance. Establishing s…
Re4+ Luminescence as a Highly Sensitive Alternative to Ruby for Optical Pressure Sensing
Yeshan Wu, Maja Szymczak, Lukasz Marciniak +5
Luminescence-based remote pressure sensing provides a powerful approach for pressure determination under conditions where conventional contact methods are difficult to implement. A…
Multiple Linear Regression-Enhanced RGB-based Luminescence Thermometry for High-sensitivity Thermal Readout
Y. Abe, M. Szymczak, Miguel A. Hernandez-Rodriguez +2
The practical implementation of phosphors for luminescence-based thermal sensing and imaging requires simple, user-friendly approaches that enable convenient and sensitive temperat…
Unlocking the Potential of Ni2+ and Ni2+-Cr3+ Synergy for Bifunctional Pressure and Temperature Optical Sensing
M. Szymczak, L. Marciniak
Reliable simultaneous optical sensing of pressure and temperature under extreme and dynamically fluctuating conditions remains a major challenge due to intrinsic cross-sensitivity…
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…
Structural Phase Transition and Cooperative Luminescence in K3Yb(PO4)2:Eu3+ for Multimodal Down-shifting and Up-converting Luminescence Thermometry
Anam Javaid, Maja Szymczak, Damian Szymanski +1
To develop a more universal luminescent thermometer that provides both high relative sensitivity and the ability to measure temperature across different spectral ranges and excitat…
