• Resumen

  • In this study, single crystals of Bi12TiO20 doped with niobium and terbium were grown by Top Seeded Solution Growth technique (TSSG). Samples with good optical quality were obtained and were investigated concerning optical absorption, optical activity, electro-optic effect, and photoconductivity. It was verified that doping with terbium and niobium changes the defects structure characteristic of sillenites, affecting in different ways the optical behavior of crystals.
