In this work, we have investigated the electronic and optical properties of the technologically important rare earth oxide compounds—X₂O₃ (X: Gd, Tb) using the density functional theory within the GGA. The band structure of X₂O₃ have been calculated along high symmetry directions in the first brillouin zone. The real and imaginary parts of dilectric functions and the other optical responses such as energy-loss function, the effective number of valence electrons and the effective optical dielectric constants of the rare earth sesquioxides (Gd₂O₃ and Tb₂O₃) were calculated.
