Crystal Growth Of Mixed Titanium Sillenites

Top Seeded Solution Growth (TSSG) technique has been used to produce Bi₁₂TiO₂₀ (BTO) and some mixed Bi₁₂Ti_0.8M_0.2O₂₀ single crystals in which Ti was substituted with M=V, Pb or Ga. Pure Bi₄₀Ga₂O₆₃ (BGaO) single crystals have been grown, too. Thermal conditions enabling growth of uniform [110] sillenite single crystals with totally flat (110) interface have been found. Influence of composition on spectral characteristics of the BTO mixed crystals has been investigated.

Keywords: sillenites, BTO, top seeded solution growth, optical absorption
