Abstract:The fundamental absorption edges of some samples of V2O5-P2O5 and V2O5-P2O5-TeO2 glasses were measured in the short wavelength part of the visible region, and it was found that the fundamental absorption of these glasses is dependent on composition and arises from direct forbidden transitions and occurs at a photon energy in the range 1.9 to 2.6 eV, depending on composition.
