✦ Synopsis

We report on ab initio calculations of the optical properties of the lead chalcogenides PbS, PbSe, and PbTe performed with a relativistic full-potential linear muffin-tin orbital method within the local density approximation. Our calculated spectra are in excellent agreement with recent ellipsometry measurements. The origin of the peaks in the spectra is discussed, as well as the effects of increasing the chalcogen atomic number.

## Abstract The reflection spectra of PbS, PbSe, and PbTe have been measured in the 14 to 26 eV region using as a source the DESY‐synchrotron. Three peaks are observed for PbSe and PbTe and two for PbS, corresponding to transitions from the outermost d‐levels of the Pb core to the conduction bands.

Starting from selfconsistent full potential LAPW results we have investigated optical matrix elements for interband transitions and the e 2 tensor. These calculations are performed for YBa2Cu307 and YBa2Cu408. The spectra are analyzed and differences are discussed with respect to the crystal structu
