The peak wave numbers of Mn3+ ion shifted toward the lower wave numbers with increasing Mno2 addition in PbO-SiO2 glasses. The refractive indices of PbO-SiO2 glasses were nearly constant. The peak wave numbers of Mn3+ ions in PbO-SiO2-K2O-Na2O glasses shifted toward the lower wave numbers with increasing [K2O]/[K2O+Na2O] ratio. The mixed alkali effect was not observed in the relation between peak wave number of Mn3+ and composition. The refractive indices shifted linearly toward the lower values with increasing [K2O]/[K2O+Na2O] ratio. No mixed alkali effect was observed clearly in the refractive index., 窯業協会誌, 93(1073), pp.58-62; 1985}, pages = {58--62}, title = {PbO-SiO_2及びPbO-SiO_2-K_2O-Na_2O系ガラス中のMn^<3+>イオンの光吸収スペクトル及びガラスの屈折率}, volume = {93}, year = {1985} }
