Abstract

The optical absorption in blown films and bulk specimens of sodium diborate glasses containing vanadium oxide based on the system [Na₂O-2B₂O₃]_1-x [V₂O₅]_x, where x = 0, 0.05, 0.10, 0.15 and 0.20, has been studied in the wavelength range 200 to 900 nm. The fundamental absorption edge has been analysed in the light of the existing models. It is found that glasses containing a higher content of vanadium have fewer defects when compared with those containing a low vanadium content. The absorption spectra are interpreted as due solely to pentavalent vanadium.
