"Using a full-relativistic version of the full-potential augmented plane wave plus local orbitals (FPAPW + lo) method within the local density approximation (LDA), we have studied the elastic, electronic and optical properties of the filled skutterudites CeFe4As12 and CeFe4Sb12. Structural parameters, including lattice constant, internal free parameters and, bulk modulus and its pressure derivative were calculated. We have determined the full set of first-order elastic constants, Young?s modulus, Poisson?s ratio and the Debye temperature of these compounds. Band structures, density of states, pressure coefficients of energy band gaps are also given. It is found that both CeFe4As12 and CeFe4Sb12 are indirect band gap semiconductors. The valence band maximum (VBM) is located at C point, whereas the conduction band minimum (CBM) is located at N point. Optical constants, including the dielectric function, optical reflectivity, refractive index and electron energy loss were calculated for radiation up to"@en . "Semari, F." . . "13" .
