4 reveal the triclinic structure with Pī symmetry. The SEM and TEM studies of the compounds show average particle size in the range of 30–50 nm. The XPS studies confirmed the 2+ oxidation state of the Co and Cu, whereas W exists in 6+ state. The Diffuse reflectance Ultraviolet–visible spectroscopy illustrates band gaps of the compounds ranging from 2.95 to 2.79 eV. The CoWO
4 shows promising photoluminescence result exhibiting strong emission intensity at 468 nm.
Mixed metal oxides of cobalt–copper tungstates were derived from solution based co-precipitation method. TEM images indicate that the particle size is in the range 30–50 nm.
