Thin-Film Luminescent UV Radiation Converters Based on Europium Chelates

This paper considers the possibility of using tris--diketonate complexes of europium in polymethylmettacrylate as luminescent UV radiation converters for widening the range of spectral sensitivity of photodetectors (including TV ones). The absolute quantum yields of luminescence have been determined. Converters for the 220–380-nm range providing a quantum efficiency of the silicon photodiode and the CCD matrix in the UV range up to 40% of the efficiency at the maximum of the spectral characteristic have been devised.
