<p></p><p>Semiconductor bandgap widening is a little investigated phenomenon in photocatalysis literature. The present investigation attempts the widening of the narrow bandgap of Ag<sub>2</sub>O to make it a semiconductor with more attractive properties. The synthesis of Zn doped Ag<sub>2</sub>O nanostructures followed a typical hydrothermal synthesis procedure. An increase in the lattice parameters of Ag<sub>2</sub>O with doping indicated the occupation of an interstitial position by the dopant metal ion. Density functional theory calculations also demonstrated the expansion of the Ag<sub>2</sub>O crystal lattice with the dopant at an interstitial location. The bandgap of the Ag<sub>2</sub>O increased to 1.65 eV for 5-mole percent doping. The DFT calculated density of states (DOS) plots also exhibit an increase in the bandgap of Ag<sub>2</sub>O after Zn doping. These doped Ag<sub>2</sub>O nanoparticles were useful in photocatalysis of methyl orange degradation under visible light irradiation.</p><p></p>
