Abstract

ZnO single crystal with a diameter of 32mm, was grown by a seeded chemical vapor transport method. X-ray diffraction technique was used to evaluate the crystalline quality. The structure defects and optic properties of as-grown and annealed ZnO crystals were compared by Raman and photoluminescence measures. It is found that the growth direction is along c-axis and FWHM is 47arcsec and 78.4arcsec in the centre and at the edge of the crystal, respectively. Quality of the crystal is improved after annealing in oxygen ambience.
