Abstract : The compounds, crystallized in the cubic form similar to sillenite structure, occur in a number of isomorphs. The well-known representatives of this family are bismuth germanium (BGO) and bismuth silicon oxides (BSo), both of which can be grown from their stoichiometric melts using Czochralsky technique. The optical examination and utilization of the isomorphs are difficult because of their incongruent melting or decomposition in solid state. At our laboratory single crystals of BSO, BGO incorporated with a variety of elements of I-VIII Periodic Table groups, as well as Bi12TiO20 (BTO), Bi38Zno58 (BZnO), Bi25FeO39, Bi25GaO39 (BGaO), Bi24GaPO40, Bi24GaPO40, Bi24FePO40 and BTO doped with Zn,Fe,V,P,Ga have been grown. The present report deals with heterovalent Ti(4+) ion substitutions of the host BTO influence on the visible transmission spectra, photoconductivity, optical power rotation and linear electrooptic factors.
