Abstract
The trivalent rare earth ions occupy the eight-coordinated (dodecahedr al) sites (D-2 point symmetry) in Gd3Ga5O12:Eu3+ crystal. The flouresc ence of Eu3+ has been investigated using laser- excited site-selection spectroscopy. It was seen three distinct sites deduced from the spect ra, one of them owing to the garnet site. The emission and excitation spectra of non-garnet site are consistent with the low symmetry point of C-2v site.
