Effect of Cadmium Ions on the Growth of CsPbxCD1 – xBr3 Nanocrystals in Fluorophosphate Glass

Perovskite CsPbxCD1 – xBr3 nanocrystals were first synthesized in fluorophosphate glass. It has been found that the incorporation of cadmium ions into the perovskite structure leads to a shift of the luminescence band from 525 to 464 nm, as a result of which the emission color changes from green to blue. A further increase in the concentration of cadmium leads to the growth of CsCdBr3 nanocrystals, which do not have their own luminescence, in the hexagonal phase.
