Fluorescence of fused silica, quartz and Borofloat 33?

  1. Jun 28, 2015 #1
    I am trying to get a glass substrate, which is transparent. However, I need this substrate to have low fluorescence. I know fused silica, quartz and Borofloat 33 are transparent but I don't know which one has the lowest fluorescence. I checked google but can't find any data that directly compares them. Any clues?

    So what you really want is material, not glass necessarily, which is maximally transparent?
    Which absorbs very few photons at any wavelength?
    I found this,which might be a good place to start. (maybe).
