Aggregation-driven growth of well-oriented ZnO nanorod arrays

摘要

Here we report an aggregation-driven growth of highly oriented and densely packed ZnO nanorod arrays through a simple natural oxidation process of pure metal zinc in formamide/water solution at low temperature. Very intense orange emission was observed in the resulting nanoparticle-built ZnO nanorods with numerous interfacial defects among their primary nanoparticles.
