A novel diamond UV photodetector with a transparent Ag nanowire (NW) electrode was fabricated. Transparent Ag NW network was spin-coated on single crystalline diamond to form Schottky contact, which had a barrier height of about 1.37 eV obtained by XPS measurements. Meanwhile, multilayered metals of Au/Pt/Ti were evaporated on the diamond sample to form ohmic contacts. Compared to the Au/Pt/Ti-Au/Pt/Ti diamond photodetector, the Au/Pt/Ti-Ag NW diamond photodetector exhibited relatively high responsivity under 220 nm (18 mA W-1), high linear dynamic range (41 dB), and short response time (0.12 s for rise time, 0.56 s for decay time). In particular, the Au/Pt/Ti-Ag NW diamond photodetector showed high photocurrent of about 200 pA at zero-bias, indicating the potential of making self-powered devices.

This study is a first-in-man clinical trial using fiber optically delivered ultraviolet light for reducing viable bacteria within indwelling tunneled dialysis catheters.
The use of ultraviolet electromagnetic radiation in the treatment of disease, usually of the skin. This is the part of the sun's spectrum that causes sunburn and tanning. Ultraviolet A, used in PUVA, is closer to visible light and less damaging than Ultraviolet B, which is ionizing.
Diamond. A crystalline form of carbon that occurs as hard, colorless or tinted isomeric crystals. It is used as a precious stone, for cutting glass, and as bearings for delicate mechanisms. (From Grant & Hackh's Chemical Dictionary, 5th ed)
Microscopy in which the image is formed by ultraviolet radiation and is displayed and recorded by means of photographic film.
Determination of the spectra of ultraviolet absorption by specific molecules in gases or liquids, for example Cl2, SO2, NO2, CS2, ozone, mercury vapor, and various unsaturated compounds. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
A rare, pigmentary, and atrophic autosomal recessive disease. It is manifested as an extreme photosensitivity to ULTRAVIOLET RAYS as the result of a deficiency in the enzyme that permits excisional repair of ultraviolet-damaged DNA.
