Effect of Cu-doping on structural, optical and photoluminescence properties of zinc titanates synthesized by solid state reaction

Undoped and Cu-doped zinc titanates were synthesized by solid-state reaction. The structural and phase transition properties were studied using powder XRD. The elemental composition of the samples was studied using EDAX analysis. Optical studies were carried by measuring photoluminescence and diffused reflectance. Bandgap energies were calculated using Tauc’s relation from the diffuse reflectance spectra. A decrease in lattice parameters, unit cell volume and bandgap energies were observed with Cu doping in zinc titanate. Photoluminescence intensity at 386 nm in the violet region was enhanced on increasing Cu dopant concentration.
