Fig. 3.
Solid-state 29Si single-pulse MAS-NMR spectra of MBGs. Q2, Q3 and Q4, obtained by Gaussian line-shape deconvolution, are displayed in green. Left: nitrate series. Right: chloride series. Two models showing the copper location in the glass network were proposed. (A) Nitrate MBGs. (B) Chloride MBGs. The outstanding concordance of calculated (in red) and experimental (in black) spectra confirms the goodness of the fitting. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
