The introduction of CsPbBr3 nanocrystals into a porous ZnO matrix leads to the appearance of a photoconductivity response in the visible spectral range. Measurement of the spectral dependences of the absorption, photoluminescence (PL), and photoconductivity showed that the shape and position of the PL peak are associated with defects in CsPbBr3. Analysis of the photoconductivity relaxation kinetics shows the possibility of accelerating the recombination of photoexcited charge carriers by more than an order of magnitude. The mechanisms responsible for this effect are discussed.
