Abstract

Electron energy loss spectroscopy installed in a transmission electron microscope was used to investigate the electronic states of LiMnVO4. The Mn-L multiplet structure of LiMnVO4 and the typical manganese oxides clearly revealed that the manganese in LiMnVO4 is divalent. The V-L spectrum showed a characteristic multiplet structure in tetrahedrally coordinated-d0 oxides, revealing that vanadium is pentavalent. The O-K spectrum was compared to that of LiMnPO4, and showed that the lowest unoccupied states of LiMnVO4 have mainly vanadium 3d character and that the bonding between vanadium and oxygen in LiMnVO4 is more ionic than phosphorus and oxygen in LiMnPO4.
