Fig. 12. Differential FTIR spectra of OSG film before and after N atom treatment for the following film temperatures: (a) 0 °С, (b) +7 °С, and (c) +15 °С. The ’+’ sign denotes the appearance of some new spectra features, while the ’−’ sign indicates a decrease of the corresponding bond concentration. A light yellow background highlights typical peaks that appear with N atom adsorption (pore surface nitridation). Reproduced with permission from [92], Copyright 2020, IOP Publishing.
