MgxZn1−xO (x = 0.0–0.20) ternary alloyed thin films have been deposited by sol-gel technique at 550 °C. The studies on the change in c-axis lattice parameter, PL spectra, optical absorption coefficient, and band gap values suggest that the solubility limit of MgO in MgxZn1−xO lies within the composition range 0.05 < x < 0.08. Optical studies on the annealed films confirm the formation of equilibrium solid solution up to x = 0.05 and the phase for the composition range 0.05 < x ≤ 0.20 to be in the non-equilibrium range.
