K. Miloslavsky, E. N. Kovalenko, V. V. Kovalenko // Functional Materials. – 2014. – V, 21, №3. – p.313-317.http://openarchive.nure.ua/handle/document/5555The absorption spectrum of the solid solutions (Cs1-xMx)4PbI6 (M=Rb,K) 0х1 is studied in the spectral range 2-6 eV at T = 90K. The formation of solid solutions (Cs1-xRbx)4PbI6 in all range of concentrations is established, the compound К4PbI6 is unstable. Linear concentration of long-wavelength exciton band parameters in the (Cs1-xMx)4PbI6 indicates the localization of excitons in PbI64- structural elements of the compounds crystal latticeenthin filmsabsorption spectraexitonsArticle
