Surface ligand networking promotes intersystem crossing in the Au 18 (SR) 14 nanocluster

Year: 2025

Type: article

Abstract: show three radiative processes, including prompt fluorescence, thermally activated delayed fluorescence and phosphorescence. The nonradiative process is partially suppressed at low temperatures, leading to enhanced photoluminescence (QY up to 9.0%) and exclusive phosphorescence was observed below 120 K. The obtained insights into the excited state energy flow and PL dynamics will benefit future design of luminescent NCs for optoelectronic applications.
