Synthesis of hierarchical PbS nanostructures capped with castor oil

We report the synthesis of castor oil capped hierarchical PbS nanostructures using piperidine dithiocarbamate of lead(II) complex as a single source precursor. The anisotropic structures of PbS were obtained at reaction temperatures of 190, 230, 270 and 300 °C. The optical properties of the PbS nanostructures show evidence of quantum confinement.
