<p>Thin film detector of ultraviolet radiation , with high spectral selectivity option, consisting of a structure placed between two electrodes, formed by the superposition of semiconductor thin films such as hydrogenated amorphous silicon and its alloys with carbon. The device is able to absorb a large quantity of UV radiation and to convert it into electric current being transpasrent to photons of longer wavelenghts. Its deposition technique allows fabrication on substrates of glass, plastic, metal, ceramic types of materials (also opaque, also flexible), on which a conductor material film has been pre-deposited. It can be fabricated on substrates of any size. Its field of application concerns: - detection systems operating in the ultraviolet spectrum and/or one or two additional band functioning in other spectral regions; - ultraviolet radiation detection systems with high rejection of radiation at greater wavelengths. For example, it finds advantageous applications in the area of laboratory spectroscopy, clinical diagnostics, clinical analyses, astrophysics, astronomy, and other applications. <IMAGE></p> |
