摘要：
The ZnO nanowire arrays were synthesized by a simple vapor-solid process. Wettability of nanowire arrays was studied by measuring contact angle. Under both oxygen plasma treatment and annealing at O-2 atmosphere, the wettability of nanowire arrays changed from hydrophobic to super-hydrophilic. By measuring the photolummescence spectra of modified samples, we affirm that the wettability conversion is not due to oxygen vacancies. It is thought that the oxygen related surface defect is the main reason to make this kind of change. (c) 2005 Elsevier B.V. All rights reserved.
