Abstract
Semiconducting vanadium zinc borate glasses with widely varying V4+/V5+ ratios have been prepared by rf sputtering in argon/oxygen atmospheres. The optical band gap ranges from 2.4 eV (70% V2O5) to 2.8 eV (30% V2O5), and the absorption edge shows an intense temperature‐dependent Urbach tail. Glasses containing V4+ show very broad crystal field absorption bands at 1.2 and 2.3 eV.This publication has 5 references indexed in Scilit:
