    摘要:

    在本文中,我们通过在薄膜上收集多晶氧化钨(WO3)纳米线得到了高灵敏度的光电探测材料,并用X射线衍射,扫描电子显微镜和透射电子显微镜分别表征了材料的结构性能。紫外可见吸收光谱计算的结果显示纳米纤维在紫外区域有很强的吸收。在WO3纳米纤维中,我们观察到了高光敏特性。一种简易的组装方法被用于制备WO3纳米线器件。我们的研究结果显示WO3可以被用于紫外光探测器。 关键词:光探测器,纳米纤维,多晶,光敏性

    Abstract:

    Herein, we report highly sensitive photodetectors, prepared by a thin film of electrospun polycrystalline tungsten oxide (WO3) nanofibers. Structural properties have been investigated by using 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 which shows a broad range in the UV spectrum. A high photosensitivity has been observed in our prepared photodetectors by using WO3 nanofibers. A facile assembly method has been used to make the device. All our investigations about structural and optoelectronics properties suggest that WO3 can be used as UV –visible photodetectors.
