“…This is in close agreement with the value reported for V 2 O 5 . 39,40 The energy gap was found to be 2.15 eV for 1%Ru@V 2 O 5 . Thus band gap for 1%Ru@V 2 O 5 has decreased by 0.05 eV.…”

“…The mechanism of electronic transport in vanadium oxides consists in the SPH between V 4+ ↔V 5+ sites [22]. Generally, in the regions where the local concentration of the V 4+ ↔V 5+ pairs is high, the conductivity is also high [10,15].…”

“…paths [6]. The optical properties of highly oriented nanocrystalline hydrated vanadium pentoxide, V 2 O 5 ÁnH 2 O, prepared by dissolving V 2 O 5 powder in hydrogen peroxide, H 2 O 2 solution reveled that two different optical gaps are present, E op1 = 0.37 eV and E op2 = 2.2 eV, respectively [7]. Generally, the fundamental electronic structure of the present system is formed by the oxygen O-2p and vanadium V-3d orbitals [8].…”

Optical transmission and reflection measurements of highly oriented nanocrystalline K x V 2 O 5 ÁnH 2 O films (0 B x \ 0.01) were studied. The optical constants such as, refractive index, the extinction coefficient, absorption coefficient, optical band gap have been calculated. The optical spectra of all samples exhibited two distinct regions of optical gap, E op1 suggesting a direct allowed transition with optical gap ranging from 0.37 up to 0.42 eV and E op2 suggesting a direct forbidden transition with optical gap ranging from 2.02 up to 2.23 eV. This indicates that K x V 2 O 5 ÁnH 2 O films have more than one type of conduction mechanism.
