Abstract
Full potential linearized augmented plane wave plus local orbital method (FPLAPW+lo) calculations were performed for LaFe4P12 in the filled skutterudite in order to investigate the optical properties and to show the origin of the different optical transitions. It is found that the band gap is indirect for LaFe4P12. Then the contribution of the different transitions peaks is analyzed from the imaginary part of the dielectric function. In contrast to recent experimental expectations, our calculations are in good agreement with experimental reflection spectra and ε1(ω) spectrum.
