Apologies for this naive non-Rietveld question, but there are many x-ray experts here :-)
Normally people use al-mylar, beryllium or other low absorbing x-ray windows, but these can be rather fragile. What about evaporating a thin layer of aluminium directly onto the scintillator? A smooth plastic x-ray scintillator would be robust enough by itself if light could be excluded from one side with some kind of x-ray transparent coating. (At present I use thin carbon-fibre x-ray windows for large areas - http://neutronoptics.com/laue.html - but there is still some attenuation.
