摘要：
In this paper we present the results of ab initio calculations of charge-transfer absorption bands in Eu3+ and Yb3+-doped CaF2 and SrF2 crystals, which are due to transitions from the top of valence band to 4f state of trivalent rare-earth ion. The density-functional theory calculations have been performed in embedded-cluster approach. It was shown that low-energy absorption band is caused by charge-transfer transitions between 2p-states of interstitial fluorine and 4f state of the impurity ion.
