Abstract:
The evolution of the luminescence blinking of single CsPbBr3 perovskite nanocrystals with a characteristic size of ∼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 g2(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 CsPbBr3 single nanocrystal.
This study was supported by the Ministry of Science and Higher Education of the Russian Federation (state assignment no. FFUU-2022-0003 for the Institute of Spectroscopy, Russian Academy of Sciences), by the Council of the President of the Russian Federation for State Support of Young Scientists and Leading Scientific Schools (project no. NSh-776.2022.1.2), and in part by the Russian Science Foundation (project no. 23-19-00884, synthesis of perovskite nanoparticles).
