Cadmium and Lead Thiosemicarbazide Complexes: Precursors for the Synthesis of CdS Nanorods and PbS nanoparticles


We report the synthesis of cadmium and lead thiosemicarbazide complexes. The single x-ray crystal structure of lead complex is reported. The cadmium thiosemicarbazide complex was thermolysed in hexadecylamine (HDA) at 140°C and 180°C to give CdS nanorods. The transmission electron microscopy (TEM) and XRay diffraction (XRD) measurements show that the reaction temperature has the influence on the size and shape of the nanorods. The lead thiosemicarbazide was thermolysed in tri-n-octylphosphine oxide (TOPO) at 240°C to yield hexagonally shaped nanoparticles of PbS. The XRD confirms a face centred cubic rock salt structure.
