The preparation of PbS nanoparticle is important in material science. Due to its predominant ionic character and low optical band gap (0.41 eV), it shows quantum confinement effect up to a larger size domain compared to other well studied semiconductor materials, such as ZnS and CdS, having predominantly covalent character. In this report, we present a simpler method of preparation of nanosized PbS in micellar medium of the surfactant AOT and spectrophotometric, fluorimetric, light scattering and electron microscopic characterization of the dispersion.
