Abstract: The optical absorption spectra of VO2+ ions dissolved in PbO-B2O3 and R2O-PbO-B2O3 glasses (R=K or Na) have been measured. By using the spectral results, the bonding mode of Pb in the glasses has been disussed. Judging from the dependence of peak position for B*2-E*n transition on the glass composition, it is suggested that although Pb behaves as a network modifier in the glasses, a part of Pb contributes to the formation of glass network. This relation is discussed on the basis of the relation between the peak wave number and ratio of four-coordinated B atoms to the total B atoms (N4B). On the assumption that the Pb ratio used in the formation of the glass network is α(x-0.2) in xPb(1-x)B2O3 glasses and (x+y-0.2) in xR2OyPbO(1-x-y)B2O3 glasses, the value of α is calculated to be 2.04.
