Spectral properties of CsPbX3 (X=Br, I) perovskite nanocrystals in borogermanate glass-ceramics

Luminescent properties of (Cs,Rb)PbBr3 perovskite nanocrystals in borate glass

“…If we assume that we were dealing with the absorption of only one type of crystals -CsPbBr3, then such shifts could be associated with a size effect: absorption in the shorter wavelength region corresponded to smaller crystals, and vice versa. 18 In such a case, if the size effect was presented only, then analogous changes should occur with the luminescence spectra.…”
