摘要：

Twinned flower-like ZnO structures have been synthesized by one-step (TAB assisted hydrothermal methods at a low-temperature as 90 degrees C. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) results disclosed a twinned flower-like morphology and hexagonal wurtzite structures. The XRD pattern and temperature-dependent PL results show a mixed structure of as-grown samples, which are confirmed by the SEM results. The CL spectrum on a single twinned flower-like ZnO structures showed an excellent optical property. Based on experimental results, self-etching and regrowth are suggested as the mechanism to grow the flower-like structures. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
