Abstract

We report on the optical behavior of pure orthorhombic perovskite LuFeO₃ ceramics in the energy range of 1.24-5 eV determined by spectroscopic ellipsometry and diffuse reflectance spectroscopy. The value of optical band gap for the LuFeO₃ was confirmed to be 2.76±0.01 eV. Main mechanism of LuFeO₃ ceramics for the band gap possibly arises from the direct electronic transitions between the major channel Fe 3d to O 2p (t_1g (π) to t_2g) charge transfer excitation.
