Cu–ZnO was synthesized by sol–gel routewith a varied copper concentration of 1, 2 and 3 mol%. The synthesizedmaterials were structurally characterized with powder X-ray diffraction and Raman spectroscopy, morphologically usinga field emission scanning electron microscope, and electronic properties were studied with UV–visible spectroscopy andphotoluminescence spectroscopy. Variation in Cu doping showed enhancement/quenching in photoluminescence of ZnO.This special characteristic is reflected in photocatalytic reduction of Cr(VI).
