Abstract Fluorescence intermittent dynamics of single quantum emitters in monolayer WSe$_{2}$ are investigated via measuring spectrally resolved time traces and time-dependent fluorescence intensity trajectories. Analysis of fluorescence trajectories and spectral shifting reveal a correlation between the fluorescence intermittency and spectral diffusion. A model of an inverse power law can be used to understand the observed blinking dynamics.
