| 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. |
