We grow the perpendicularly oriented ZnO nanorods under hydrothermal conditions at 90°C with and without UV ligh bias on the nominally undoped ZnO thin film deposited by DC reactive magnetron sputtering. The different morphological structures were visualized and analyzed by scanning electron microscopy (SEM). The crystalline configuration and the structural quality were investigated by X-ray diffraction and Raman spectroscopy. The surface properties of ZnO nanorods were examined by X-ray photoelectron spectroscopy. The defect-related photoluminescence observed as a broad band at wavelengths 550-650 nm was significantly reduced after plasma hydrogenation whereas the exciton-related peak at 378 nm increased significantly. The strong suppression of the F+related defects was observed after plasma hydrogenation using the electron paramagnetic resonance (EPR).
