| Abstract: | PbS is a direct bandgap IV-VI semiconductor with a bandgap of 0.41 eV and an exciton Bohr radius of 18 nm at room temperature.It has exceptional third-order nonlinear optical properties and applications for optical devices.In this paper,we synthesize PbS nanoparticles in aqueous solution using different capping agents.UV-Vis spectra show that the sample is much more stable.The nanoparticles are investigated by UV-Vis absorption spectrum and X-ray diffraction pattern.As a result of the nanoparticle size redu... |
