IR- and raman spectra of silver-palladium resistive films sensitive to the light circular polarization sign

The Raman and infrared studies of silver-palladium resistive films sensitive to the light circular polarization sign are presented. The films are produced from a special paste at different burning temperatures. In the Raman spectra of the films obtained at the burning temperature of 878 K the scattering line with corresponding to the oxide palladium vibrational mode B$_{\mathrm{1g}}$ is found. It is established that both the Raman shift and the scattering line width depend on the exciting radiation power density. It is shown that the scattering line intensity observed decreases with the increasing of the burning temperature of the film. Based on the reflection infrared spectra analysis it is established that the significant contribution to their picture yield the vibrations of the oxides containing in the initial paste, herewith the palladium oxide vibrations do not appear explicitly.
