摘要
We report the synthesis ofZnO nanowires grown on glass by spin coating and using a commercial microwave oven. 10 mM solutions of zinc acetate dehydrate and 12propanol were spin coated on glass at 2000 rpm for 60 s. A seed layer was obtained after three layers of spin coating. Vertical ZnO nanowires were then grown by dipping the substrate in an equimolar solution of zinc nitrate hexahydrate and hexamethylenetetramine subsequently, films were heated with a commercially microwave oven at different power settings (140, 350 and 700 W). The ZnO nanowires were characterized optically and morphologically. Scanning electron microscopy analysis showed that the size of ZnO nanowires was 50 nm in diameter and 500 nm in length. XRD patterns and IR spectra revealed the presence of Zn(OH)2 on the films, when low power in the microwave oven was utilized. The ZnO nanowires bandgap energy was obtained from optical transmission spectra.
