| 英文摘要 | The structure of glasses in the systems (100 - x)B2O3-xPbF(2) (x = 30, 40, and 50) and 50B(2)O(3)-(50 - x)PbO-xPbF(2) (x = 5, 10, 15, 20, 25, 30, 35, 40, and 45) has been studied by solid state NMR and EPR spectroscopies.-On the basis Of B-11 and F-19 high resolution solid state NMR as well as on B-11/F-19 double resonance results, we develop a quantitative structural description on the atomic scale. F-19 NMR results indicate a systematic dependence of the fluoride speciation on PbF2 content: At low x-values, F- ions are predominantly found on BO3/2F- units, whereas, at higher x-values, fluoride tends to be sequestrated into amorphous domains rich in PbF2. In addition, both pulsed EPR studies of Yb3+ doped glasses and photophysical studies of Eu3+ doped samples indicate a mixed fluoride/borate coordination of the rare-earth ions, and the absence of nanophase segregation effects. |
