The V 2O 5 sol was fabricated by ultra fast quenching.The vanadium with low valence (V 4+ ) was found in V 2O 5 xerogel films by XPS analysis.The technology of oxygen top blown was applied to analyze the XPS spectrum difference of V 2O 5 xerogel when the powder of V 2O 5 was melting in air or in oxygen atmosphere.The results show that the different melting atmosphere has certain influences on the chemical valence of V 2O 5 xerogel.
