摘要：

The absorption and circular dichroism (CD) spectra of La3Ga5SiO14 langasite crystals doped with Pr3+, Ho3+, and Er3+ ions have been studied in the wavelength range of 350-700 nm. The electronic transitions of these ions, which replace La3+ ions in the 3e position with the symmetry 2, are observed in the spectra. All transitions are active in both the absorption and CD spectra. The dipole strengths D (om), rotational strengths R (om), and anisotropy factors g have been calculated for well-resolved bands. Some features are noted for the spectra that were obtained, and their relationship with the structure disorder is considered.
