“…On the other hand, TiO 2 nanostructures have also emerged as very promising materials for optoelectronic devices due to their excellent physical and chemical properties, such as high melting point, chemical inertness, physical stability, direct bandgap (rutile 3.0 eV), high photoconversion efficiency, and photostability. Self-powered UV photodetectors based on a photochemical cell have been fabricated using a liquid I - /I 3 - redox couple electrolyte and a nanocrystalline TiO 2 film [19] or a multilayer TiO 2 nanorod-assembled cloth/nanorod array-based electrode [20]. Impressive performances were observed in these UV detectors.…”

Large-area vertical rutile TiO2 nanorod arrays (TNAs) were grown on F/SnO2 conductive glass using a hydrothermal method at low temperature. A self-powered ultraviolet (UV) photodetector based on TiO2 nanorod/water solid–liquid heterojunction is designed and fabricated. These nanorods offer an enlarged TiO2/water contact area and a direct pathway for electron transport simultaneously. By connecting this UV photodetector to an ammeter, the intensity of UV light can be quantified using the output short-circuit photocurrent without a power source. A photosensitivity of 0.025 A/W and a quick response time were observed. At the same time, a high photosensitivity in a wide range of wavelength was also demonstrated. This TNA/water UV detector can be a particularly suitable candidate for practical applications for its high photosensitivity, fast response, excellent spectral selectivity, uncomplicated low-cost fabrication process, and environment-friendly feature.

“…Self-powered photodetector devices based on compact TiO 2 film and nanostructured TiO 2 film have been fabricated and studied by different groups. 21,22 All these devices display a high photosensitivity, excellent spectral selectivity, and fast response. However, most of the self-powered photodetectors are constituted with inorganic oxide semiconductors and liquid electrolyte, which makes them unstable and inconvenient for practical application.…”

Individual semiconductor nanowires (NWs) TiO2 were successfully welded together by using novel one-dimensional (1D) Au80Sn20 (mass ratio) nanosolders at the nano scale for the first time. The nanosolders were electrodeposited into nanoporous templates to form 1D structure, and their morphology, crystal structure, chemistry and elemental electronic states were systematically characterized. Individual Au80Sn20 nanowires were proved to consist of mixed crystal phases, including Au5Sn phase with trigonal structure, AuSn phase with hexagonal structure and little SnO2 phase produced by oxidation of the surface portion. Chemical analysis indicates that the composition is Au80Sn20. The testing of welding capability either in situ TEM or in situ SEM by nanomanipulators and Infiltration experiment reveal a good wet ability and diffusion ability between the Au80Sn20 nanosolder and TiO2 nanowire. It is believed that our work contribute a special nanosolders for future nanoscale welding techniques, which also make the bondings of titanium-based semiconductor oxide nanomateirals at the nanoscale a reality.
