Abstract
Abstract
We obtained ZnO crystals with different morphologies through a simple hydrothermal method by adjusting the solution pH. We characterized the ZnO crystals by means of scanning electron microscopy and found several different morphologies, including strip-like, flake-like, cone-like, and six-sided prism shaped particles. The reaction mechanism of the ZnO crystal growth was also investigated. The absorption properties of the ZnO samples were studied using ultraviolet–visible spectroscopy. The studies of the optical properties indicated that the absorption peaks of all samples were located at 377.9 nm. However, there was some variation in the absorption spectra of the ZnO particles with different morphologies.
