Single‐Particle FRET Probes Heterogeneity in the Ligand Shell of Colloidal Perovskite Quantum Dots

ABSTRACT The functionality of colloidal quantum dots (QDs), whether in fundamental studies, optoelectronics, or emerging quantum technologies, critically depends on their surface chemistry, with organic ligands influencing nearly every aspect of their behavior. Whereas the inorga...

Unconventional Biexciton Dynamics in Superradiant Perovskite Quantum Dots Driven by Many‐Body Correlations

ABSTRACT Excitons and biexcitons emission traits, for example, quantum yield, lifetime, and coherence, govern device performance metrics including brightness, optical gain thresholds, and the efficiency of single‐ and entangled‐photon generation. Biexcitons are conventionally und...
