The emission properties of ZnS nanobelts synthesized through thermal evaporation were investigated by means of scanning near-field optical microscopy. The photoluminescence (PL) images of single nanobelts exhibited a bright line along their length. The local light emission spectra measured over the bright lines showed a green emission peak around 535 nm, which was in good agreement with a PL peak obtained for an ensemble of the nanobelts. From careful scanning-electron-microscopy observations of identical nanobelts, we found that the observed green emission is related to line or planar defects of the ZnS nanobelts.
