Description
Summary: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[([Cl.sub.1-x][Br.sub.x]).sub.3] and CsPb[([Br.sub.1-x][I.sub.x]).sub.3] due to the aftergrowth treatment of CsPb[Br.sub.3] 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. DOI: 10.1134/S106378261710013X
