Microwave hydrothermal synthesis and optical properties of flower-like Bi2MoO6 crystallites
Source abstract
Abstract
Abstract Flower-like Bi 2 MoO 6 crystallites were successfully synthesized by the microwave hydrothermal process using Bi(NO 3 ) 3 ·5H 2 O and Na 2 MoO 4 ·2H 2 O as source materials and adding hexamethylene tetramine (HMT) as a template. X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM) were used to characterize the products. Ultraviolet–visible (UV–vis) spectroscopy was employed to study the optical properties of Bi 2 MoO 6 . Results show that the product morphology is flower-like on adding the template. These flower-like Bi 2 MoO 6 crystallites are a self-assembly of many thin nanoplates. HMT plays an important role in the formation of the flower-like morphology. UV–vis absorption spectra of all the Bi 2 MoO 6 samples show strong photoabsorption properties from the ultraviolet region to the visible-light region with wavelength shorter than 500 nm. The band gap of flower-like Bi 2 MoO 6 crystallites displays a slight red-shift compared with the Bi 2 MoO 6 plate-like structures.
