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 (t1g (π) to t2g) charge transfer excitation.
