摘要：

Novel zinc oxide (ZnO) microprisms doped with Mg have been synthesized on Mg (NO3)(2)-coated Si (111) substrates successfully by a thermal chemical vapor deposition method. The as-prepared Mg-doped zinc oxide single-crystal microprisms were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), and photoluminescence (PL). The results show that the microstructures consist of hexagonal pyramids tips and hexagonal prisms. The whole structure is a perfect single crystal and has preferred growth along the [0001] direction. PL reveals ultraviolet (UV) emission at 388 nm and a strong green light emission peak at 500 nm. Mg-doped microprisms will provide an improvement for novel electronic and optical devices. In addition, the growth mechanism of the special Mg-doped ZnO microstructure is proposed based on a solid vapor approach. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
