摘要：

Detailed analysis of the spectroscopic properties of the YAlO3 crystals doped with manganese ions has been performed. The exchange charge model of the crystal field was used to calculate the crystal field parameters and energy levels of the Mn4+ and Mn5+ ions in YAlO3. It was shown that both ions contribute to the formation of the absorption spectra. The calculated energy levels are in good agreement with the main observed absorption peaks. Comparison of the Racah parameters B for both ions in YAlO3 with those for free ions shows a significant role played by the covalent effects, especially for Mn5+.
