Abstract
This work is devoted to the synthesis and investigation of the stability of cesium lead halide CsPbBr3 perovskite nanocrystals for the problems of electroanalytical chemistry and in particular for the development of electrochemiluminescent sensors. The photoactivation and photodegradation of nanocrystals in solutions and polymer thin films are studied. Electrodes based on glassy carbon and modified by thin films containing CsPbBr3 nanocrystals are developed. The possibility of electrochemiluminescence signal generation with modified electrodes during the reaction with aqueous solutions of coreactant is studied. The important role of photoactivation of CsPbBr3 containing thin films of nanocrystals for obtaining the effect of electrochemiluminescence in them is revealed.
