Aligned arrays of ultrathin, high‐quality ZnO nanotubes (see Figure) have been synthesized via hydrothermal growth methods on Si that has been pre‐coated with a thin film of ZnO. The nanorods are single‐crystalline, with typical wall thicknesses and outer diameters of 5–15 and 20–40 nm, respectively. Annealing the arrays in vacuum causes enhancement of UV photoluminescence.
