A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

Light‐Coupled Nanocrystal Solids

ChemistryEurope, Volume 4, Issue 3, March 2026.
Light‐coupled nanocrystal solids are self‐assembled superlattices or doped solids engineered for emission rather than charge transport, spanning optically dense to dilute regimes and enabling collective or single‐photon optical functionalities. Defining the optical coupling and engineering these nanomaterials will expand applications of colloidal ...
