摘 要：<正> Raman, IR spectra, RDF and visible spectrum were used to study the glass structure and the valence states of niobium ions in P2O5-Nb2O5-Li2O noncrystalling system. The colour-changing mechanism was studied. For 10Nb2O5xP2O5（90-x）Li2O （x=40,45,50,55） system glasses, it was known that the glass colout changing from light gold-yellow to blue with increasing is aroused by the Nb3+ ion increasing, not by the change of niobium ion coordination.
