X-ray emission and absorption spectra of carbon nitride films prepared by laser ablation

X-ray emission and absorption spectra of carbon nitride films prepared by l aser ablation were measured. The carbon x-ray spectra of films obtained in a nitrogen atmosphere were different from those of a film prepared in vacuu m. It was found from DV-X alpha molecular orbital calculations on x-ray spe ctra that the films obtained in a nitrogen atmosphere contained bonding bet ween carbon and nitrogen atoms, This was supported by the Fourier transform IR spectra.
