Notes:
We have measured the absolute quantum yield for alkali halides and the spectral transmission for alkaline earth fluoride windows to find an optimized bandpass combination for a solid state ultraviolet (UV) photon detector for inverse photoemission. The best resolution achieved is 0.33 eV (full width at half-maximum), being obtained with the NaCl photocathode–BaF2 window combination. This, however, leads to a rather low quantum efficiency of 0.3%. The combination NaCl–SrF2 chosen for our detector offers a resolution of 0.42 eV (full width at half-maximum) with a maximum quantum efficiency of 2.5% at 9.50 eV photon energy. © 1997 American Institute of Physics.
