MgO-doped ZnO films, metastable in nature, are deposited by combustion flame pyrolysis, as this is one of the suitable methods for fabricating such nonequilibrium films. Experiments to alloy ZnO with MgO have been carried out, aiming to expand the band-gap to the ultraviolet region. Structural and optical studies show that Zn1−xMgxO films with various x values (x = 0.2, 0.3, 0.33, and 0.4) could be obtained and the band-gap of ZnO could be tuned from 3.26 eV to 3.76 eV.
