In this paper, ZnO doped with Cu and Mn ions with different molar ratios were prepared by hydrothermal method at 200 ℃ for 24 hours. Zn0.95-xMn0.05CuxO powders with different doping ratios were synthesized. Zn0.93Mn0.05Cu0.02O, Zn0.89Mn0.05Cu0.06O, Zn0.85Mn0.05Cu0.10O and Zn0.80Mn0.05Cu0.15O powders were obtained. XRD tests showed that all four samples were incorporated Cu2+ and Mn2+ at Cu2+:Mn2+=6:5 (Zn 0.89Mn0.05Cu0.06O) powder CuO and Mn3O4 peak strength are the highest. The EDS spectra show that it contains Zn, Cu, and O elements. SEM shows that the crystal structure of the product obtained by different doping ratios is different, where there are both regular crystals with shapes similar to boxes and flocs, irregular flakes, and very compact tiny crystals, which can be seen at Cu2+:Mn2+=6:5.
