a The schematic diagram for the synthetic procedure of the CdIn2S4 nanocrystals with sulfur vacancies. b PXRD patterns. c ESR spectra. d Core-level XPS spectra of S 2p for CdIn2S4 and Vs-CIS-500. e The SEM image of Vs-CIS-500. Inset is the reconstructed shape based on the BFDH theory. f The HADDF-STEM image of Vs-CIS-500. Inset is the atomic structure of CdIn2S4 (\(0\overline 1 1\)) with In and S as truncated atoms. g The density of states for CdIn2S4 bulk and CdIn2S4 (\(0\overline 1 1\)) with surface sulfur vacancies. h Different charge density image for the CdIn2S4 (\(0\overline 1 1\)) with surface sulfur vacancies (isosurface set at 0.04e Bohr−3); yellow and cyan regions represent electron accumulation and depletion, respectively.
