γ LiAlO_2 doped with Fe^(3+) in the tetrahedral site has been examined by extended X-ray absorption fine structure (EXAFS) analysis, and Mössbauer and optical spectroscopy. The isomer shift (IS) is −0.026 mm/s (Fe-Pd); the quadrupole splitting (QS) is 0.62 mm/s. Anisotropic optical absorption is prominent at ∼391, 452, and 463 nm. The K-edge absorption spectrum shows a prominent absorption near 7,113 ev typical of tetrahedrally coordinated Fe^(3+).

Additional Information:© 1983 Springer-Verlag. Received October 5, 1982. The X-ray absorption data were collected at the Stanford Synchrotron Radiation Laboratory which is supported by the National Science Foundation through the Division of Materials Research and the National Institutes of Health through the Biotechnology Resource Program in the Division of Research Resources. They LiAl0_2 : Fe^(3+) crystals were synthesized and Mössbauer spectra obtained at UCLA during the Ph.D. dissertation work of one of the authors (G.A. Waychunas). Support from W.A. Dollase (NSF grant DES 74-19918) during this period is gratefully acknowleged. Optical spectroscopy was supported by NSF grant EAR 79-04801.
