Visible-blind and solar-blind ultraviolet detectors for flame and oil spill detection

Visible-blind and solar-blind ultraviolet detectors for flame and oil spill detection are useful for solving the technical challenge of operating these detectors with a large background radiation of sunlight. UV detection in the wavelength range of 210-300 nm is useful for flame, oil spill and missile detection, and traditional approaches include wide band gap semiconductor UV photodetectors and vacuum-based photoemission detectors. We are investigating more effective and less costly technologies for UV detection, including self-assembled visible light filters and solid-state photoemission detectors based on metal nanoparticles with plasmonic enhanced responsivity.
