Abstract :
Superposition model (SPM) is used to calculate zero field splitting (ZFS) parameters (ZFSPs) and crystal field parameters (CFPs) of Cr3+ doped EuAl3(BO3)4 (EAB). Substitutional and interstitial sites for Cr3+ ion in EAB crystal and distortion are taken into account for calculation. The determined ZFSPs are in reasonable agreement with the experimental values when distortion is taken into account. The optical energy band positions for Cr3+ in EAB are found using CFPs obtained from SPM and CFA package. The results suggest that Cr3+ ions substitute EAB lattice at Al3+ sites.
