Tunable Room‐Temperature Polaritons in the Very Strong Coupling Regime in Quasi‐2D Ruddlesden–Popper Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
The study reports widely tunable room‐temperature exciton polaritons in quasi‐2D perovskite microcavities operating at the transition between strong and very strong coupling regimes. These experimental and theoretical insights explain the peculiar scaling behavior of the light–matter coupling in our tunable system, paving the way for future tunable ...

Unlocking Spin Dynamics: Spin‐Orbit Coupling Driven Spin State Interconversion in Carbazole‐Containing TADF Emitters

open access: yesAdvanced Optical Materials, EarlyView.
This study explores overlapping charge transport mechanisms in TADF materials and identifies spin‐orbit coupling as the dominant mechanism for triplet‐to‐singlet transition in carbazole‐based cyanoarene emitters. Computational investigations reveal a second spin‐orbit‐coupling‐mediated reverse intersystem crossing pathway, significantly enhancing the ...

Photoluminescence Properties of Type‐II GaSb/GaAs Quantum Rings

open access: yesAdvanced Photonics Research, EarlyView.
This study examines the magneto‐optical properties of GaSb/GaAs quantum rings (QRs) using photoluminescence spectroscopy. Recombination dynamics in single‐ and ten‐layer structures are analyzed through activation energy extraction, optical absorption profiling, and observation of a strong excitation‐induced blue shift. Carrier lifetime is also increase
