Dear all,   
      
   I'm looking for sensitive photon detector for near UV range in order to detect   
   cobtinuous nitrogen fluorescence emission between 300 and 400 nm  with maximum   
   around 340 nm.   
   I know from literature that PMT could do the job, and notably in photon   
   counting mode ; but I would like to have more robust and maybe cheaper   
   alternative with solid-state detectors.   
   I don't necessarily need fast time response since the source is not pulsed...   
   Has anybody already tried Avalanche photodiode or Silicon Photomultiplier in   
   this specific UV range for low-light application ?   
      
   Thanks,   
      
    Eric
