The invention belongs to the field of inorganic nano-materials, and discloses a
zinc oxide-
polyaniline sandwiched
ultraviolet photoelectric
detector and a preparation method thereof. The
detector is formed by assembling a layer of
zinc oxide nano-sheet array on ITO and a layer of
polyaniline nano-wire on the
zinc oxide nano-sheet array by taking ITO conductive glass as a substrate. The preparation method of the
ultraviolet photoelectric
detector comprises the steps of: preparing a layer of zinc oxide nano-sheet array on the ITO substrate by adopting an electrochemical method at first, then, preparing the
polyaniline nano-wire through a chemical oxidization method,
spinning the prepared polyaniline nano-wire on the zinc oxide nano-sheet array, and finally, assembling all products, so that the
ultraviolet photoelectric detector is prepared. Due to the
nanometer size and the morphology of the material, the relatively large specific surface area is obtained;
a site, where the material acts with
ultraviolet light, is increased; and therefore, the ultraviolet photoelectric detector has the characteristics of being steady in performance, high in sensitivity and short in
response time.
