Abstract
The optical isotropy of the cubic garnet was overcome by crystal-site selective excitation and fluorescence spectroscopy. Thus the symmetries of the crystal-field states of the free ion levels7F J and5D4 could be determined. On this basis a crystal field analysis was performed to derive the crystal-field parameters for the Tb3+ ions replacing the Y3+ ions on the D2 sites.
