Nanocrystalline PbS thin films were prepared by simple and cost effective chemical spray pyrolysis (CSP) technique. Lead acetate and Thiourea were used as a source of Pb and S respectively. The structural and optical properties of the PbS films were studied. Structural cubic phases of the PbS thin films were identified by X-ray diffraction with preferential orientation along (200) plane. The average grain size of the film is calculated using Scherer’s relation and it is in the order of nanometers. The optical properties of the films were studied by measuring their optical Absorbance and transmittance as a function of wavelength. UV-VIS spectrum of the film showed that the optical band gap decreases with increase in the molarities of precursor solution. The surface morphological studies of the films were analyzed by scanning electron microscope..

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.
