We demonstrate a simple method to achieve growth of vertically aligned ZnO nanostructures on a Si (100) substrate with/without the use of a metal catalyst. Well-aligned single crystalline ZnO nanorods have been grown on silicon substrates by a single-step process without using any metal catalysts or a pre-deposited ZnO seed layer that was a requirement for such synthesis. The mean diameter of the nanorods is ~120 nm. In addition, x-ray diffraction measurements show that ZnO nanorods had single crystalline atomic structure and pure compositions with no any impurities. More importantly, from photoluminescence spectra of the nanorods strong and narrow excitonic emission and extremely weak deep level emission were observed, indicating that the nanorods are of high optical quality. And flower-like ZnO nanostructures were fabricated on Au coated Si substrate.
