Abstract
Measurements are reported on the fluorescence and excitation spectra of Fe 3+-doped LiGa 5O 8 in the ordered phase. Spectral determinations were made with powder samples containing 0.01 to 1% atomic weight of Fe 3+, within the temperature range 300 K to 25 K. A comparison is presented between the optical properties of trivalent iron in lithium gallate and in lithium aluminate, LiAl 5O 8, both in their ordered phases. The best fit with crystal field parameters B, C, and Dq, yields the following values for these parameters: Dq = 906 cm -1, B = 594 cm -1, and C = 3 737 cm -1. As is the case with LiAl 5O 8:Fe 3+, the Stokes shift in LiGa 5O 8:Fe 3+ is very large, 3 624 cm -1, although somewhat smaller than the 4 300 cm -1 seen in LiAl 5O 8:Fe 3+.
