The influence of annealing temperature on the structural and optical properties of porous ZnO nanobelts

Abstract

In this paper, by controlling the annealing temperature, different morphologies porous ZnO nanobelts could be obtained. Scanning electron microscopy, X-ray diffraction, and PL measurement were applied to analyze the morphologies, structural and optical properties of porous ZnO nanobelts. With the annealing temperature increased, the nanopartiles as the constituent parts of ZnO nanobelts became large gradually. Based on the experiment results, the possible formation mechanism of porous ZnO nanobelts was discussed.
