摘要

采用籽晶辅助化学气相传输法生长得到φ32mm ZnO单晶体. X射线衍射表明晶体沿c轴方向生长, 结晶质量较好: 中心部位摇摆曲线半高宽47arcsec, 边缘部分为78.4arcsec. 利用Raman谱、光致发光谱等研究了ZnO晶体退火前后的缺陷和光学性质, 表明经氧气氛退火后晶体缺陷明显减少, 晶体质量进一步提高.

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.

Key words： ZnO; chemical vapor transport method; X-ray rocking curve; Raman spectrum; photoluminescence
