Fabrication, Structures and Properties of Quasi One-dimensional ZnO Toothed - nanostructures

Keywords： nanostructures

Uniform ZnO toothed-nanobelts and nanocombs were fabricated respectively through pure zinc powder evaporation without catalyst at temperature of 600-650 ℃. Scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) observations show that such ZnO nanostructures have several types in morphology, and all of them are single crystalline. The experimental results reveal that the growth of the ZnO nanostructures was controlled by vapor-solid mechanism. Room temperature photoluminescence spectra of the toothed- nanobelts show a UV emission at ～ 390 nm and a broad green emission with 4 subordinate peaks at 455-495 nm.
