普通的硅光探测器,如硅光电池或硅光电二极管等仅能对可见光和近红外光响应。利用无色透明紫外荧光涂料或油墨能吸收紫外线而发出红色荧光的特点,把紫外荧光涂料涂在普通硅光电池的表面,向紫外光区拓展了其光谱响应范围。采用光声光谱技术测量了荧光硅电池的光谱响应特性,研制了荧光差分式紫外光探测器。 Ordinary silicon photodetectors, such as silicon cells or silicon photodiodes, respond only to visible and near-infrared light. The use of colorless transparent UV fluorescent coating or ink can absorb ultraviolet light and emit red fluorescence characteristics, the UV fluorescent coating on the surface of ordinary silicon photovoltaic cells, UV spectral region to expand its response. The spectral response of fluorescent silicon cell was measured by photoacoustic spectroscopy. A fluorescence differential UV detector was developed.
