Abstract

Optical spectroscopy methods are used to study the spectra of some oxygen-octahedral ferroelectrics - $LiNbO_3$ and $LiTaO_3$. Study of the role of $BO_6$ octahedron by using spectroscopic methods can cast light on the many physical phenomena that place in $LiNbO_3$ and $LiTaO_3$. For these crystals, absorption edge, band gap, Urbach constants and phonon energy were found.
