Undoped and Fe doped Zn0.96Cu0.04O (Fe = 0.01, 0.02, 0.03 and 0.04) alloys were successfully synthesized by sol-gel method. The hexagonal wurtzite structure of ZnO could not altered by Cu and Fe doping and it was confirmed by X-ray diffraction spectra. The initial non-equilibrium substitution of Fe (0.01) led to increase the lattice parameters such as d-value, cell parameters, volume and bond length. But the lattice parameters were decreased after Fe = 0.01 due to the proper substitution of Fe3+ ions. The changes in lattice parameters, average crystal size, peak position and peak intensity confirmed the Fe substitution into ZnCuO lattice. The change in surface morphology by Fe doping was stu..View full abstract
