Influence of time on Zinc Oxide growth by hydrothermal method

Zinc oxide (ZnO) structures were synthesized via hydrothermal method by the different times of growth from 20, 30, 40, 50 and 60 minutes. The effect of different growth time on crystallize size and optical properties of ZnO structures were studied and investigate. Then, the samples were characterize...
