In this experiment, pure, Y³⁺ doped ZnO and Cu²⁺ + Y³⁺ co-doped ZnO were synthesized by a solution combustion method. The Y³⁺ dopant concentration was fixed in 3%wt. and the Cu²⁺ dopant concentrations were 0, 1, 2, 3, 10, and 20%wt. The XRD spectra showed that the original hexagonal wurtzite structure of ZnO is conserved after doping process, an increasing red shift until 10%wt. Cu²⁺ doping and decrease at higher Cu²⁺ doping and also, the chemical creation of the news Y₂O₃ and Y₂Cu₂O₅ phases. The behavior of the photoluminescence of the samples as a function of Cu²⁺ doping reveal that the green emission band of the ZnO is quenching and the ZnO UV emission intensity decrease notably for all Cu²⁺ doping. The scanning electron microscope analysis of the Cu²⁺ + Y³⁺ co-doped ZnO samples reveal the existence of grains agglutinated forming like-spheres particles. However, the nano-sized characteristic of the crystals is confirmed.
