Abstract

High-density aligned ZnO nanorods films were grown on zinc-covered Si wafer by using hydrothermal method in the alkali solution containing hydrogen peroxide (H₂O₂). The growth process involves the oxidation of zinc into oxidized zinc species cluster in the alkali solution containing hydrogen peroxide (H₂O₂) and the ZnO nanorods growth process in which oxidized zinc species provide seeds for nucleation site of nanorods ZnO crystal growth during hydrothermal process. The hydrogen peroxide plays a key role in formation of oxidized zinc species cluster. Room temperature PL spectrum and Raman spectrum of the sample are also studied and indicate that there is a very low concentration of oxygen vacancies in the highly oriented ordered ZnO nanorods.
