Abstract: Fe/Co co-doped Zinc oxide was prepared by using hydrothermal method. Refinement of recorded X-ray diffractograms was done by Rietveld method by using MAUD. It shows that all the samples have a hexagonal structure with space group P63mc and the average crystallite size of the samples lie between 49-79 nanometers. Presence of some secondary phases were also detected. Rietveld analysis data reveals that the density of the doped and co-doped ZnO is more than the pristine ZnO. The goodness of fit value ranges from 1.3875-1.7519. The unit cell volume decreases for the doped and co-doped ZnO as the value of lattice parameter decreases with doping and co-doping. Decrease in the interplaner spacing values may be because of the strain developed in the lattice due to doping and co-doping.
