چکیده انگلیسی
ZnO nanorods were grown by a simple near room temperature, chemical solution method on ZnO-seeded silicon substrates. Study of the ZnO nanorods over different growth times by electron microscopy methods revealed that the resulting ZnO nanorods were single crystalline with a highly preferential growth perpendicular to the substrate and a very good c-axis alignment. The size of the nanorods increased with increasing growth time. The growth mechanism is briefly discussed. Post-annealing in oxygen slightly improved the surface roughness of the ZnO nanorods. Photoluminescence experiments at 1.6 K revealed a major emission peak of the nanorods at around 3.36 eV which is attributed to the band edge transition of ZnO, while defect-related emission is relatively weak.
