The optical properties of metal oxide nanorods

Original language description

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. Thus, using hydrogen plasma instead of high temperature annealing, we have achieved the defect passivation at room temperature. The strong suppression of the F+related defects was observed after plasma hydrogenation using the electron paramagnetic resonance (EPR). This makes evidence for strong influence of the surface defects on the photoluminescence properties of the ZnO nanorod.
