Optical properties of Bi12TiO20 doped with Al, P, Ag, Cu, Co and co-doped with Al+P single crystals

Abstract
Large optically homogeneous photorefractive Bi12TiO20 (BTO) single crystals doped with Al, P, Ag, Cu, Co and Ala P-co-doping were obtained by the Top Seeded Solution Growth Method (TSSG) in a Bi2O3 solution. A strong bleaching eAect was observed for the Al, P, Ag and Ala P-doped crystals, whereas doping with Cu and Co induced a strong photochromic eAect and increased the absorption coeAcients in the red spectral region. Al, P, Ala P-doped crystals increased the values of optical rotator power, while Cu and Ag-doped crystals exhibited a strong decrease in optical activity in comparison with non-doped BTO. The influences of doping elements on the optical rotation power are discussed on the basis of two structural elementary cell units ‐ MO4 tetrahedra and BiOn polyhedra. ” 2000 Published by Elsevier Science B.V.
