摘要
报道了PbO和KF之间形成玻璃。研究了其组成对热稳定性、密度、摩尔体积、折射率、光学带隙、乌尔巴赫能和Pb2+发射光谱的影响。在KF影响热稳定性的同时，PbO的含量由于形成强的- Pb - O - Pb -共价键而显著影响光学性质。PbO含量的增加还导致声子辅助的非辐射衰变，从1P1和3P1水平到3P0水平，导致1P1→1so0发射显著降低。
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.
