(a) XRD pattern taken from the synthesized products revealing the existence of hexagonal and cubic ZnS. (b) The typical SEM morphology of the synthesized bulk of ZnS nanowires.
TEM and HRTEM images of the ZnS nanowires: (a) A low-magnification TEM image of several ZnS nanowires. The selected area diffraction pattern (shown in the inset) taken from a nanowire suggests the existence of twinning in the nanowire. [(b) and (c)] High-magnification TEM images of an individual ZnS nanowire. (d) HRTEM image of an individual ZnS nanowire (insert shows the lattice resolution of the nanowire).
The EDX spectrum of an individual ZnS nanowire.
(a) UV-vis absorption spectra of the ZnS nanopowders and periodically twinned ZnS nanowires. (b) Room-temperature PL spectra of the ZnS nanopowders and periodically twinned ZnS nanowires.
