Optical and Structural Characterization of Antimony Doped Zinc Oxide Single Crystal

The optical and structural study of the antimony doping in zinc oxide (ZnO) single crystal (001) performed by atomic diffusion is presented. Diffusion was carried out with a temperature of 1000 degrees C for periods of 1 and 2 hrs from a solid source prepared by partial oxidation of antimony, characterization of each step process was performed by photoluminescence (PL), x-ray diffraction (XRD) and high resolution x-ray diffraction (HRXRD). The characterization by PL shows the effect of antimony doping on the emission band intensity attributed to reduction of oxygen vacancies by antimony introduction. The results of XRD showed that antimony source has a Sb2O3 crystalline phase. Reciprocal space maps of doped samples revealed the low dimensional structural modification of single crystal produced by the introduction of antimony. Results indicate that antimony is introduced fully into surface of ZnO and produce low dimensional changes on structure.
