Sumario:Room-temperature photoluminescence (PL) in V(2)O(5) nanospheres with zero-like dimensional structure was investigated. A large number of V(4+) oxidation states in the nanospheres were observed by X-ray photoelectron spectroscopy (XPS) measurements. The nanospheres revealed high PL intensity compared with previous studies. In particular, they showed intense ultraviolet (UV) PL near a wavelength of 396 nm (3.13 eV). The intense UV PL was attributed to the enhanced transition probability due to the large number of V(4+) (3d(1)) oxidation states. The PL properties showed strong dependencies on the oxidation states and their distribution.
