文摘

In this work, impurity cross-section of Co doped Bi₁₂MO₂₀ (M = Si, Ti) is presented in the spectral region 1.5–2.25 eV. Einstein coefficients of both induced absorption, spontaneous and stimulated emission are determined as guides for the application of doped BSO and BTO in holography domains. Transition dipole moment and refractive index of Co doped crystals are calculated. The Lattice Compatibility Theory is also applied to the investigated samples.
