چکیده انگلیسی
Resonant soft X-ray emission (SXE) spectra have been measured for a series of excitation energies at the V Lα and O Kα bands of divanadium pentoxide, V2O5. In addition, a near-edge X-ray absorption fine structure (NEXAFS) spectrum at the V 2p and O 1s edges has been also recorded to aid the assignment of the features seen in the SXE data. The V Lα SXE spectrum of V2O5 consists of two distinct components that can be assigned to the V 3deg-like states strongly hybridized with the O 2pÏ-like states and to the V 3dt2g-like states weakly hybridized with the O 2pÏ-like states. The resonant SXE spectra recorded at photon energies close to the position of the V LIII edge revealed Raman-like features with an energy loss of 7 eV similar to charge transfer states previously observed by Schmitt et al. [T. Schmitt, L.-C. Duda, M. Matsubara, M. Mattesini, M. Klemm, A. Augustsson, J.-H. Guo, T. Uozumi, S. Horn, R. Ahuja, A. Kotani, J. Nordgren, Phys. Rev. B 69 (2004) 125103] for the V6O13 oxide.
