Paper Title:
Investigation of Morphology and Photoluminescence of Hydrothermally-Grown ZnO Nanorods Grown on Substrates Pre-Coated with ZnO Nanoparticles
  Abstract

We show that the rod-like morphology of hydrothermally-grown ZnO nanorods can be obtained on any substrate, pre-coated with ZnO nanoparticles, when pH<7.3 or pH>10.1. When pH>10.1, three types of morphology, from uniform nanorods to large clustered rods, can be distinguished based on the solubility of zinc. In line with classical thermodynamics, the density of nanorods increases when the solubility of zinc decreases. We also report that the orange defect peak photoluminescence can be reduced, while the UV peak increased by decreasing the pH of the growth solution.
