Abstract
The 2F7/2←2F5/2 transition of the cerous ion has been observed in solid solutions of cerium(III) fluoride in cadmium fluoride. The band center is at about 2250 cm—1, in good agreement with the free‐ion value of 2253.0 cm—1. The crystal field splitting of the band appears to be enhanced by the effect of the interstitial fluoride ions which compensate for the excess positive charge of Ce3+ in Cd2+ positions. Addition of NaF, which eliminates the interstitial fluoride ions, decreases the splitting. Praseodymium and neodymium ions in CdF2 also showed absorption bands.Keywords
