Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles

open access: yesAdvanced Optical Materials, EarlyView.
Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.

Thermal‐Energy‐Boosted Luminescence for Precise Optical Thermometry in Eu/Tb‐Doped ScNbO4

open access: yesAdvanced Optical Materials, EarlyView.
This paper presents a novel phosphor for high‐performance optical thermometry utilizing thermal‐energy‐assisted luminescence boosting. The samples are prepared by incorporating Eu‐doped ScNbO4 and Tb‐doped ScNbO4 powders into a PDMS matrix. Under blue light excitation, the sample exhibits a stunning emission color change from green to red as the ...

Understanding the Role of Fabry‐Perot Resonances in Maximizing Absorption for Ultrathin Sn Halide Perovskite Optoelectronic Devices

open access: yesAdvanced Optical Materials, EarlyView.
A design principle is presented that maximizes absorption in ultrathin (tens of nanometers) Sn halide perovskite optoelectronic devices by aligning their intrinsic absorption wavelengths with Fabry–Pérot (FP) resonances. The ultrathin FASnI3 devices exhibit increases open‐circuit voltage, reduces dark current, and high photocurrent, yielding high ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,
