Electronic Structure of h-WO3 and CuWO4 Nanocrystals, Harvesting Materials for Renewable Energy Systems and Functional Devices

摘要：

The electronic structure of hexagonal WO3 and triclinic CuWO4 nanocrystals, prospective materials for renewable energy production and functional devices, has been studied using the X-ray photoelectron spectroscopy (XPS) and X-ray emission spectroscopy (XES) methods. The present XPS and XES results render that the W 5d- and O 2p-like states contribute throughout the whole valence-band region of the h-WO3 and C11WO4 nanocrystalline materialls, however maximum contributions of the O 2p-like states occur in the upper, whilst the W Sd-like states in the lower portions of the valence band, respectively.
