Doped semiconductor nanoparticles have greater impact on their structural and optical properties due to quantum size effects. Zn doped PbO nanoparticles are synthesized by chemical precipitation with Lead (II) Acetate and Zinc Acetate Trihydrate as precursors. The synthesized particles are characterized using X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), UV-Visible spectroscopy (UV-Vis), Photoluminescence spectroscopy (PL), Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive Spectroscopy (EDS), High Resolution Transmission Electron Microscopy (HRTEM). XRD studies reveal that the average crystallites are in the range of 23 and 40 nm and Specific Surface Area (SSA) is also determined. Zn doped PbO Nanocrystals exhibit the blue shift around 250 nm in the absorption spectra and the band gap is around 3.87 eV. FT-IR shows the metal vibrations and EDS spectrum reveals the elemental concentrations. The results imply that Zn doping enhance the structural and optical properties of PbO nanocrystals..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
