7. Surface properties; MDO 285 Fig. (7.19) shows the high resolution scan of the O1s peak, which was asymmetric, of glass MOF001_v (65TeO2-10Na2O-25ZnF2 mol. %), which was melted for 2 hours with fluorinated ZnF2. Fig. (7.19): High resolution XPS spectrum of O1s peak from cleaved surface of glass MOF001_v (65TeO2-10Na2O-25ZnF2 mol. %), with deconvoluted components due to: bridging and non-bridging oxygens (O1s), OH (O1s) and M=O species (O1s). Table (7.7) summarises the quantitative analysis from the high resolution scans, and for comparison, the actual atomic % batched and theoretical peak positions from the NIST XPS database.

(7.14). Fig. (7.20) shows the XPS wide scan of the polished surface (i.e. un-cleaved) of glass MOF001_v (65TeO2-10Na2O-25ZnF2 mol. %), which was melted for 2 hours with fluorinated ZnF2, for comparison.
