| Outline of Final Research Achievements |
The local structure around germanium of LiGe2(PO4)3 with the glass and the natrium super ionic conductor (NASICON)-type glass ceramic was investigated. While the X-ray absorption near edge structure spectra at the Ge K absorption edge of the glass ceramic indicated a distinct peak with a shoulder at higher energy sides, the glass exhibited a broad spectra. In the radial structure function obtained by Fourier transform of the extended X-ray absorption fine structure oscillation, the Ge-O correlation peak of the glass was observed at the shorter distance in comparison with that of the glass ceramic. These results suggest that the local structure around germanium in the glass is different from that of the glass ceramic composed of the GeO6 octahedral units.
