A novel ZnO nanostructures on glass substrates were successfully synthesized using VLS method.
Using Cu thin film as catalytic on glass substrate assisted ZnO nanostructure growth.
The growth of 1D ZnO nanorod and nanoneedle arrays was investigated.
The growth mechanism of ZnO nanorod and nanoneedle was controlled by varying the growth temperature and growth time.
The crystal quality of ZnO nanostructures strongly depends on the growth temperature and growth time.
