Abstract

The method of vacuum ultraviolet (VUV) spectroscopy were used to study the optical properties of ABO(3) ferroelectrics (LiNbO3, LiTaO3, BaxSr1-xNb2O6, Ba2NaNb5O15, SrTiO3, BaTiO3, PbMg1/3Nb2/3O3, KTaO3, KNbO3) in the photon range from 1.0 eV to 35.0 eV at temperatures T=10-600 K. The results were used to calculate the optical junctions, density of states and energy spectra of these compounds. A comparison of the experimental results with theoretical calculations shows the fundamental significance of the BO6 octahedron in the formation of the energy spectra of ABO(3) ferroelectrics.
