Abstract: The paper deals with the results of experimentally determined influence of the chemical composition change of pure Ge-Se-Te glasses systems with the rare earths elements additions (Pr, Er and Ho in oxide or pure metal form) on electrical and dielectric properties of the glasses. We used chalcogenide bulk glasses Ge20Se80-xTex for x ∈ (0, 5, 10, 15) prepared by systematic replacement of Se by Te. We wanted to find how electrical and dielectric properties of chosen chalcogenide glasses change with the change of content and form of rare earths. We carried out the measurements at different temperatures from 20 °C to 170 °C. Results show that the inhomogeneity and defects in the measured glasses have had an impact on the measured dielectric parameters.
