Abstract
The low temperature emission spectrum of the Cr3+ ion in the cubic lattice K2NaAlF6 has been measured. A detailed analysis of the vibrational structure observed leads to the conclusion that the 2Eg and 4T2g excited states of the CrF3−6 ion are displaced along the eg, a1g, and possibly the t2g coordinates. A similar analysis of the emission spectrum of K2NaGaF6:Cr3+ is possible, and values of five of the six internal vibrational modes of the CrF3−6 ion have been deduced.Keywords
