(a) FTIR absorption spectra of hybrid silica films (MTES-TEOS) in the 1250–950 cm−1 wavenumber range as a function of dose; the arrows indicate the change in intensity of the bands with the increase of the dose. At higher doses the Si—O—Si band at 1070 cm−1 increases in intensity while the shoulder at 1150 cm−1 decreases. Colours of the curves: magenta, as-deposited (unexposed reference sample); red, 94 J cm−2; cyan, 188 J cm−2; blue, 377 J cm−2; black, 754 J cm−2; green, 1508 J cm−2; navy, 3015 J cm−2. (b) Contour representation of the data in (a). The x-axis represents the wavenumber and the y-axis the dose scale in seconds. The colour scale corresponds to absorbance.
