In this article, we explore the coupling between the localized surface plasmon of gold nanorods and the excitonic states of methylammonium lead iodide (MAPbI3) perovskite quantum dots. Using single-molecule fluorescence microscopy, time-resolved fluorescence spectroscopy, transient absorption spectroscopy, and finite-difference time-domain simulations, we reveal the origin of exciton-plasmon-coupled blinking suppression and emission intensity enhancement in the gold nanorod-MAPbI3 quantum dot system.
