Nt. Gorton et al., EXPERIMENTAL-ANALYSIS OF THE COMPOSITE BLUE CATHODOLUMINESCENCE EMISSION IN QUARTZ, Journal of luminescence, 72-4, 1997, pp. 669-671
Phase-tuned polarised emission spectra of high-purity quartz crystals
have been measured which give direct experimental evidence of the comp
osite nature of the broad-band emission and the number and spectral po
sition of the components. The results enable a spectrum to be reproduc
ed theoretically by summation of Gaussian component bands of experimen
tally determined number, position and phase.
