Fluorescent cardboards as UV-screens

The spectra are Hg spectra, photographed from a Canon 10D, light source is a Hg high pressure lamp, the entrance slit is imaged with a quartz lens via a reflection grating on different screens:
There are the spectra of the screens, in order from left to right
As you can see, these cheap cardboards with fluorescent paint are well suited and only cost a few dollars for half a square meter.

If I remember correctly, x-ray fluorescence was first observed by Röntgen in barium platinocyanide painted onto a cardboard screen.
