In this study, a Schottky-type ultraviolet (UV) photodetector based on double-layered nanostructured TiO2/Au films was fabricated. Double-layered titanium dioxide (TiO2) nanostructures composed of one layer of TiO2 nano-flowers on one layer of TiO2 nanorods on fluorine-doped tin oxide (FM) pre-coated glass substrates were synthesized via a convenient hydrothermal method using titanium butoxide and hydrochloric acid as the starting precursor, without involving the use of any other surfactants and catalysts. A granular-shaped thin-layer of Au film using vacuum sputter coating technique was subsequently deposited on TiO2 for the formation of Schottky-type photodetector. The as-fabricated Schottky device showed various photocurrent responses when irradiated with different wavelength of UV light. This suggests that the newly-developed photodetectors have promising potential for identifying different UV light wavelengths. (C) 2017 Elsevier B.V. All rights reserved.
