Structural and optical properties of MgxZn1-xO (x = 0.05) films grown on microscopic glass substrates by sol-gel technique were investigated. Zinc acetate dihydrate, Magnesium acetate as starting precursors and ethanol as a solvent were used to prepare the gel solution. These deposited films were annealed at three different temperatures and characterized by X-ray Diffractometer (XRD), Scanning Electron Microscopy (SEM) and UV-VIS Spectrophotometer for studying structural and optical properties. Energy dispersive analysis by X-ray (EDAX) was used to determine incorporation of Mg content into ZnO. EDAX spectra clearly show the incorporation of Mg into the ZnO films. XRD spectrum reveals that the deposited Mg doped ZnO films were polycrystalline in nature. Crystallinity of these films was found to be increase with increase in post annealing temperature. Optical band gap of MgxZn1-xO annealed films was found to be increased from 3.33 to 3.37eV as estimated from both transmission spectra and the absorption coefficients. The band gap was observed to be blue shifted with increasing annealing temperature.

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.
