Abstract

Bi₁₂TiO₂₀ crystals doped with Nb atoms ranging 0.05 - 0.2 wt.% are grown from non-stoichiometric melts by modified Czochralski pulling technique. Doping studies showed that Nb⁵⁺-ions occupy tetrahedral sites in sillenite lattice. Experimental results on spectral dependent characteristics, such as, absorption, photochromic effect, photoconductivity and electrooptic efficiency are presented. Comparison with similar properties of Bi₁₂TiO₂₀ crystals doped with another pentavalent atoms (V,P) is discussed. A relationship of these characteristics with local structural defects in doped Bi₁₂TiO₂₀ lattice is proposed.
