dc.description.abstractCastor oil contains a range of fatty acids of which a high proportion is ricinoleic acid. We report the syntheses of CdS and PbS nanoparticles by the thermal decomposition of ethyl xanthate complexes of cadmium and lead in castor oil using the heat-up synthesis technique. The castor-oil capped CdS nanoparticles showed cubic zinc blende and wurtzite crystal structures and displayed band gap range of 2.63–2.84 eV. The CdS formed near spherical clusters of nanocrystals with average particle size of 6.78 (±1.89) nm. The castor-oil capped PbS nanoparticles showed a rocksalt crystal structure and displayed an average band gap of 0.85 eV. The PbS showed variety of morphologies of nanostructured particles ranging from rods to belts. The average width and length of the PbS nanobelts observed were 22.2 (±2.3) nm and 225.9 (±23.3) nm respectively.
