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…
Constructing a bifunctional platform based on Mn2+-doped Mg2Y8(SiO4)6O2 phosphors for multi-parameter optical thermometry and manometry
Zhiyu Pei, Shuailing Ma, Maja Szymczak +4
Series of the Mn2+-doped Mg2Y8(SiO4)6O2 phosphors were synthesized. Upon excitation at 408 nm, these phosphors exhibited intense orange emission originating from Mn2+, with concent…
Unlocking Dynamic Luminescent Mapping of pH with Sustainable Lignin-Derived Carbon Dots with Multimodal Readout Capacity
Maja Szymczak, Jan Hočevar, Jernej Iskra +4
In this work, we demonstrate the use of CQDs synthesized from lignin - currently one of the most abundant and underutilized by-products of paper and pulp production - for advanced…
From the up-converting multimodal luminescent thermometer to ratiometric visual power density meter based on Er3+,Yb3+ emission
Anam Javaid, Maja Szymczak, Lukasz Marciniak
This study demonstrates that thermally induced variations in the spectroscopic properties of Na3Sc2(PO4)3:Er3+, Yb3+ can be effectively harnessed for multimodal remote temperature…
Bridging Two Dimensions: Luminescent Sensors at the Intersection of Temperature and Pressure
Lukasz Marciniak, Maja Szymczak, Przemyslaw Wozny +1
Luminescence thermometry and manometry are exponentially growing areas dealing with the optical detection of temperature and pressure, respectively, being appealing alternatives fo…
Exploring the Interplay Between Formation Mechanisms and Luminescence of Lignin Carbon Quantum Dots from Spruce Biomass
Jelena Papan Djaniš, Maja Szymczak, Jan Hočevar +5
This study investigates the intricate relationship between the formation mechanisms and luminescent properties of lignin-derived carbon quantum dots (LG-CQDs) synthesized from spru…
