Аннотация
Synthesis and also the structural and photoluminescence properties of nanocrystals with natural faceting of the “cesium–lead–halogen” system with crystalline structure of the perovskite type are examined. The possibility of continuously changing the position of the maximum in the photoluminescence spectrum in the wavelength range of 400–700 nm is demonstrated. Features of the formation of the continuous series of solid solutions CsPb(Cl1–xBrx)3 and CsPb(Br1–xIx)3 due to the aftergrowth treatment of CsPbBr3 nanocrystals as a result of anion exchange at room temperature are studied. The corresponding range of frequency change for the maximum of the photoluminescence spectrum amounts to 410–690 nm.
