We present a unique ultrasonication based method for the preparation of copper sulphide nanoparticles in ambient air using a single precursor complex, which acts as a source of both metal and sulphur. The nanoparticles of 3.31 nm have been prepared successfully by the method and characterized using powder X-ray diffractogram (PXRD), dynamic light scattering (DLS) analysis UV-Vis spectroscopy and fluorescence spectroscopy. The results proved that copper sulphide nanoparticles of hexagonal structure (covellite phase) can be prepared by sonochemical method within a very short reaction time of ~5 min. The band gap of the nanomaterial has also been calculated from absorption spectrum and was found to be 2.36 eV.
