    摘要: A nuclear radiation detection system using narrowband UV crystal filters is disclosed. Since the photons produced during the decay of β- and γ-radiation can be detected in the spectral range of about 200-350 nm (the ultraviolet range), UV filter based photo sensors are utilized for detection. The nuclear radiation detection system comprises an optical assembly capable of focusing on a source of radiation, a UV filter assembly having a narrowband UV crystal filter and positioned to receive light transmitted through the optical assembly, and a light detector positioned to receive light transmitted through the UV filter assembly. The narrowband UV crystal filter is fabricated from crystals selected from the group consisting of nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate. The nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate may be doped to achieve even narrower band filter. The radiation detection system can be used to monitor contamination in a nuclear plant or a nuclear waste dump site. It may also be used for surveillance of contamination in case of a nuclear accident.

    摘要: A solid state light emitting device having a plurality of semiconductor finger members with side walls perpendicular to a substrate. Multiple quantum wells are formed on the side walls, and are also perpendicular to the substrate. Each multiple quantum well is sandwiched between the side wall of a finger member and a second semiconductor member of a conductivity type opposite to that of the finger member. Ohmic contacts are applied to the finger members and second semiconductor member for receiving a voltage. The device is GaN based such that emitted light will be in the UV region.
