Influence of W5+ ions on the optical properties of doped Bi12TiO20
Abstract
There have been studied single crystals of undoped and doped Bi12TiO20 with two concentrations of W5+ (2.62 × 1017 cm-3 and 2.62 × 1018 cm-3). There have been obtained absorption spectra in the energy range of 10,482-15,408 cm-1 by classical measurements. There have been determined the cross-section (σa) of the impurity absorption and the oscillator strength of d-d transitions. There have been calculated the refractive index of doped crystals and the concentration of Ti3+ ions in an undoped sample through an experiment.
