Abstract
Colloidal nanocrystals that are capable of mass production with wet chemical synthesis have long been proposed as color-tunable, scalable quantum emitters for information processing and communication. However, they constantly suffer from spectral diffusion due to being exposed to a noisy electrostatic environment. Herein we demonstrate a cavity-photon interface (CPI) which effectively suppresses the temperature-activated spectral diffusion (SD) of a single perovskite nanoplatelet (NPL) up to 40 K. The spectrally stabilized single-photon emission is achieved at a specific emission direction corresponding to an inhibited dipole moment of the NPL as the result of the Fano coupling between the two photon dissipation channels of the NPL. Our results shed light on the nature of the SD of perovskite nanocrystals and offer a general cavity quantum electrodynamic scheme that controls the brightness and spectral dynamics of a single-photon emitter.
