In this review, we provide a brief overview of the recent progress achieved on the plasmon-enhanced fluorescence technique for the study of exciton-plasmon interactions using time-resolved photoluminescence spectroscopy. Quantum emitters situated in regions of localized field enhancement are excited by the enhanced electromagnetic field intensity. During the emission process, both the radiative decay rate and nonradiative decay rate can be increased by the enhanced electromagnetic field. These can be distinguished using two methods, either by neglecting the excitation rate enhancement when the excitation wavelength is far from the surface plasmon resonance or by assuming that the enhancement of the excitation is the same as the radiative decay rate. This review aims to provide a comprehensive understanding of the time-resolved photoluminescence spectroscopy of exciton-plasmon coupling dynamics.
