- The results of room-temperature optical study of single-grain simple icosahedral ZnMgHo quasicrystals are presented. The dielectric function epsilon(omega) of the quasicrystals was measured by spectroscopic ellipsometry technique in the spectral range of 0.1 - 7 eV. The si-ZnMgHo optical response is a superposition of the free-electron Drude-type contribution and that of the interband transitions. The experimental epsilon(omega) spectra are well simulated within a framework of the band structure hypothesis. The deduced parameters of the si-ZnMgHo electron energy spectrum are close to their values determined previously in an analysis of the si-ZnMgHo photoemission data.
