Low-Temperature Growth of Well-Aligned ZnO Nanorods by Chemical Vapor Deposition

1D single-crystalline zinc oxide nanostructures are promising for nanoscale optoelectronic applications. Here a simple chemical vapor deposition method for the growth of well-aligned ZnO nanorods (see Figure) at low temperature is demonstrated. The nanorods, which grow on fused silica and are preferentially oriented in the c-axis direction, are strongly UV light emitting, peaking at around 386 nm at room temperature.
