Abstract

Tb₃Sc₂Al₃O₁₂-TbScO₃ eutectic crystallizes in a rodlike microstructure, and its potential to exhibit photonic bandgap has been presented tentatively. In order to model its optical properties there is a need for precise determination of the optical properties of its component materials in a wide spectral range. Spectroscopic data in the range from 0.6 to 6.5 eV (190-2100 nm) were obtained using spectroscopic ellipsometer UVISEL, Horiba Jobin-Yvon. The measurement was completed with mid infrared reflection data using Bruker FTIR spectrometer in the spectral range from 7500 to 550 cm^-1. Optical functions were obtained using fitting of the data with model dielectric function fulfilling the Kramers-Kronig dispersion relations. Obtained optical functions enable to model the optical properties of self-organized eutectic micro- and nanostructures.
