Hydrothermal synthesis and optical properties of zinc silicate hierarchical superstructures
چکیده انگلیسی

A simple hydrothermal method has been developed for fabricating hemimorphite zinc silicate, Zn4Si2O7(OH)2·H2O (ZSO). Three-dimensional ZSO hierarchal superstructures are deposited on the Si substrate. The product is characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscope. The characterization results of the sample show individual ZSO hierarchical architectures are assembled by many well-aligned and highly ordered rod bundles. The morphologies of the rod bundles within the ZSO hierarchal superstructures can be conveniently controlled, by selecting the different reactant concentrations, with excellent reproducibility. The luminescence spectra showed that the ZSO hierarchical superstructure had a stronger emission peak at 436 nm and a weaker emission peak at 418 nm.
