| Abstract: | The crystal structure and some optical properties of slightly substituted solid solutions of Bi1-xGdxFeO3, Bi1-xNdxFeO3 and Bi1–x–yGdx LayFeO3 as ceramic compound samples at x < 0.2 and х + y < 0.2 have been estimated by means of X-ray diffraction and reflection spectroscopy in visible region of spectrum. Mentioned Bi1-xGdxFeO3, Bi1-xNdxFeO3 compounds show at room temperature the dominant crystal structure with space group of R3c type at concentration of the doping element x < 0.1 and also detect the presence of the optical absorption due to electronic transitions with wave length of the order of 0.4–0.5 μk, 0.6 μk, 0.8 μk and 1.1 μk due to the transitions of the three-charge iron ions, positioned in the distorted oxygen octahedra. |
