Regularly shaped, single-crystalline ZnO nanorods with Wurtzite structure.

A convenient route at ambient conditions was employed to prepare narrow-dispersed ZnO nanorods in terms of size and morphology. Transmission electron microscopy and X-ray diffraction were used to characterize the structurally uniform and well-proportioned products. The as-prepared specimen exhibits strong ultraviolet exciton emission at 385 nm and disappearance of visible defect emission.
