Glass formation between PbO and KF is reported. The influence of composition on thermal stability, density, molar volume, refractive index, optical band gap, Urbach energy, and Pb2+ emission spectra are presented. While KF influences thermal stability, the PbO content markedly influences the optical properties due to the formation of strong -Pb-O-Pb- covalent linkages. Increasing PbO content also results in phonon assisted nonradiative decay from 1P1 and 3P1 levels to 3P0 level leading to a marked decrease in the 1P1→1S0 emission.
