(a) Stable dispersions in toluene under excitation by a ultraviolet lamp (λ=365 nm). (b) Low- and high-resolution transmission electron microscopy images of CsPbBr3 NCs; corresponding scale bars are 100 and 5 nm. (c) PL spectra of the solutions shown in (a). (d) Optical absorption and PL spectra of a ca. 400-nm-CsPbBr3 NC film.
