CCD广泛用于可见光和近红外波段的成像,为了使CCD也能在紫外和极紫外波段成像,波长转换十分有用。采用对此波段敏感的荧光物质,使辐射到CCD上的紫外和极紫外光转换成可见光,CCD便可对其成像。研究了产生荧光的过程和条件以及用于把紫外和极紫外光转换成可见光的荧光物质需要满足的条件后,发现水杨酸钠、四苯基-丁二烯、六苯并苯和路玛近比较合适,并简明介绍了它们的特性和制备方法。评述了该领域的荧光物质物质的应用前景以及需要改进的方面。
CCD is widely used in the visible and near-infrared imaging, in order to make the CCD can also be in the UV and EUV band imaging, wavelength conversion is very useful. Using this wavelength-sensitive fluorescent material, the UV and EUV light that is radiated onto the CCD is converted into visible light, which is then imaged by the CCD. After investigating the conditions and conditions under which fluorescence is generated and the phosphors used to convert UV and EUV to visible light, sodium salicylate, tetraphenyl-butadiene, hexacene and Luma Nearly suitable, and brief description of their characteristics and preparation methods. The application prospects of fluorescent substances in this field are reviewed and the aspects that need improvement are also reviewed.
