TLDR
In this paper, the impact of fuel to oxidizer molar ratios (F/O = 0.5-2.0) on luminescence properties is explored, and it is shown that higher F/O inhibits Eu3+ and promotes Eu2+ formation, which improves the quality of the blue phosphor.About:

X-ray line broadening from filed aluminium and wolfram
G.K Williamson,W.H Hall +1 more
TL;DR: In this paper, the authors used a Geiger counter spectrometer to measure the changes in intensity distribution in the spectra of cold worked aluminium and wolfram and found that the line breadths may be attributed to simultaneous small particle size and strain broadening, the latter predominating at the higher Bragg angles.
