摘要：
We reported highly sensitive photodetectors, prepared by a thin film of electrospun polycrystalline tungsten oxide (WO3) nanofibers. Structural properties have been investigated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. UV-Visible absorption spectra was used to calculate the band gap of the electrospun nanofibers, showing a broad range in the UV spectrum. A high photosensitivity has been observed in the prepared photodetectors by WO3 nanofibers. A facile assembly method has been used to make the device. The results suggest that WO3 can be used as UV-visible photodetectors.
