摘要: Core-hole spectroscopy such as X-ray absorption spectroscopy (XAS) is useful to determine the electronic structure of strongly correlated and strongly hybridized compounds such as vanadates. Monazite-type LaVO 4 and perovskite-type LaVO 3 are good candidates to elucidate the electronic structure through the vanadium L 2, 3 edge. LaVO 4 was prepared by sol-gel acrylamide polymerization and solid-state reaction. LaVO 3 was obtained by reduction of LaVO 4 using Zr as gatherer. Monoclinic crystal phase for LaVO 4 and …
