| dc.description | Optical spectroscopy methods are used to study the spectra of some oxygen-octahedral ferroelectrics - namely LiNbO<sub>3</sub> and LiTaO<sub>3</sub>. It is shown that for the measured range of E and T, varies exponentially with the photon energy following the empirical Urbach rule. A study of the role of the BO<sub>6</sub>-octahedron by using spectroscopic methods can cast light on the many physical phenomena that take place in LiNbO<sub>3</sub> and LiTaO<sub>3</sub>. For these crystals, absorption edge, band gap, Urbach constants and phonon energy are found. |
