a TEM images of BCSO NSs. The inset indicates the hydrodynamic size distribution of BCSO NSs. b HRTEM image of lattice fringes. c Corresponding SAED pattern of superlattice BCSO NSs. d EDS mapping images and (e) XRD pattern of BCSO NSs. f Structural model of BCSO NSs. HRTEM images accompanied by the corresponding FFT patterns, and schematic representations of the atomic distribution of BCSO NSs oriented along (g) [001] and (h) [010] zone axes, respectively. The spatial arrangement of atoms within the (i) Bi-O and the ( j) Cu-Se layers along the [010] zone axes. k Bi 4 f, (l) Cu 2p, (m) Se 3 d and (n) O 1 s XPS spectra for BCSO NSs.
