Abstract

Zinc Oxide (ZnO) nanomaterials were grown on glass substrate through the non-catalytic horizontal vapor phase crystal growth at temperature of 600⁰C, 800⁰C, 1000⁰C, and 1200⁰C. The growth time was varied from two to eight hours in two-hour increments while the ramp time was adjusted from 20 minutes (fast) to 80 minutes (slow). Scanning electron microscopy reveals that nanowires with lengths of a few microns and width of 40-130 nm are synthesized at lower temperatures and nanoblades of width 200 nm are formed at higher temperatures. Moreover, the length of the grown nanostructures increased from 5 to 10 microns as the growth time is increased from two to eight hours. Slow ramping rate was found to yield nanostructures that have smaller widths while less unreacted ZnO powder were observed at higher temperature and longer growth time.
