The dependence of the concentration of lead and calcium Raman spectra (RS) films of lead titanate-calcium Pb1-xCaxTiO3 (PCT), it is determined that the substitution of Pb Ca on the general nature of the spectra does not change even when x = 0.45 Raman spectra correspond to tetragonal ferroelectric phase, which is implemented in pure PCT. It was revealed that the soft mode component A1(TO) in the film-lanthanum titanate lead Pb0.9La0.1TiO3 (PLT) has a frequency of 280 cm-1 and significantly shifted to lower frequencies with an increase in the content of La.
