Summary: Manipulating photocarrier dynamics for luminescent materials is of fundamental importance for controlling the luminescent properties of optoelectronic devices. This study demonstrates the enhancement and prolongation of photoluminescence through interfacial engineering, which enables resonant coupling between localized surface plasmon and exciton. The photocarrier dynamics at the interface are mediated by plasmon-induced hot electron transfer (PHET) and plasmon-induced resonant energy transfer (PIRET) processes, which can be actively switched on and off by varying the excitation laser wavelength. These findings are highly significant for actively manipulating photocarrier dynamics in perovskite luminescent devices.
