| Abstract: | Zinc oxide (ZnO) nanowires (NWs) have been synthesized using zinc nitrate and hexamethylenetetramine by templateless, surfactant-free and seedless aqueous solution route. The morphology of ZnO NWs was considerably affected by growth time: a longer reaction time results in the formation of ZnO NWs. Structural analysis of the synthesized NWs showed an average diameter of 20–30 nm length of several micrometers and single-crystalline wurtzite hexagonal structure. Photoluminescence studies of ZnO NWs showed a strong green emission peak at 585 nm. |
