    摘要: An electron filtering layer placed on a photocathode of a UV light detector allows to selectively filter out electrons generated from a photoconversion of long wavelengths. The filter may be tuned by selecting the material and the thickness of the electron filtering layer. By means of the filtering layer, background noise due to visible parts of the spectrum may be efficiently suppressed. Applications of the invention include a solar-blind flame and/or smoke detector.
