FIG. 1.

Visible Raman spectra of the films deposited at various laser intensities: (a) , (b) , (c) , (d) , (e) , and (f) . The inset represents an enlargement of the CN triple bond signal detected at around for spectrum (f).

FIG. 2.

Evolution of the intensity of the Raman band at as a function of the sum of the areas under the and Raman bands (the data are normalized for film thickness). The solid curve shows a quadratic fit of the data.

Image of FIG. 3.
FIG. 3.

Variation of the factor determined from the fitting of the Raman spectra as a function of laser intensity. A typical fit of a Raman spectrum with two Gaussian peaks representing the and Raman bands is shown in the inset.
