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 ...

Host Tuned Luminescence Lifetime Thermometers for Imaging Boiling Thermal Dynamics Through Bubbles

open access: yesAdvanced Optical Materials, EarlyView.
The bismuth to vanadate distance is adjusted in solid solutions of ytrrium and scandium orthovanadate to design a lifetime‐based luminescence thermometer with optimal temperature resolution at 100 °C. It is applied on the surface of a boiling channel to observe the thermal signatures of bubble growth and liquid film dry‐out.

Bi–Sb Co‐Alloying Tunes Photoexcited State Dynamics in (4FPEA)4AgBi1−xSbxI8 Layered Double Perovskites through Structural Confinement

open access: yesAdvanced Optical Materials, EarlyView.
Lead‐free double perovskites are emerging alternatives to lead‐halide analogues, leveraging low toxicity and highly tunable chemical compositions. These materials possess unique carrier dynamics, often governed by self‐trapped exciton (STE)‐mediated recombination.
