High Photoluminescence Quantum Yield and Tunable Luminescence Lifetimes in the Sub‐Second Range of CaS:Eu2+ Phosphors for Tracer Based Sorting

open access: yesAdvanced Materials Technologies, EarlyView.
Efficient plastic waste sorting is crucial for circularity. Advanced methods using lanthanide photonic tracers enhance recycling beyond near‐infrared sorting. Europium(II)‐doped phosphors, with high stability and long luminescence decay, improve tracer detection in sorting systems, enabling precise identification of different plastic materials ...

Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions

open access: yesAdvanced Materials Technologies, EarlyView.
This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters

open access: yesAdvanced Optical Materials, EarlyView.
Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.

Below 1% Reflectance for Black GaAs Surface Prepared by Facile Two‐Step Wet Chemical Treatment: Hydrogen Peroxide and Water

open access: yesAdvanced Photonics Research, EarlyView.
Black GaAs surface which decreases light reflectivity forms in surprising way when GaAs is kept first in hot hydrogen peroxide solution and then in hot‐water solution. To increase performance of many photonic devices (e.g., solar cell, light emitting diode (LED), photodetector), it is essential to decrease light reflection at device interfaces ...
