Abstract: The evolution of the luminescence blinking of single CsPbBr$_3$ perovskite nanocrystals with a characteristic size of $\sim$25 nm during photodegradation has been experimentally investigated. It has been demonstrated that the blue shift of the luminescence peak and a decrease in the average luminescence intensity are accompanied by the increasing role of nonradiative Auger processes underlying the charging mechanism of blinking. A method based on the analysis of photon antibunching $g^2(0)$ and exciton and biexciton recombination rates is used to determine the blinking mechanism. The data obtained have made it possible to reveal a transition from the trapping to charging blinking mechanism with a change in the sizes of a CsPbBr$_3$ single nanocrystal.
