ZnO Nanowire Arrays prepared on Quartz Glass Substrate by Wet Chemical Method

ZnO nanowire arrays were prepared on quartz glass substrate by wet chemical method. The morphology, crystal structure and optical properties of ZnO nanowires were characterized by scanning electron microscopy, X-ray diffraction and spectrophoto meters. The results show that the ZnO nanowires were hexagonal wurtzite structure, the diameter and length of nanowires respectively were 60-200 nm and 0.1-3 μm. Photoluminescence(PL) peak value of the nanowires was 380 nm, and a strong absorption peak appeared in PL patter from 340 nm to 380 nm, indicating that the nanowires had excellent ultraviolet response characteristic. ZnO nanowire arrays had high orientation.
