Abstract
The xZnO–(100 – x)NaPO3 vitreous system is investigated in this contribution by advanced 1D/2D magnetic resonance spectroscopies. The glass network organization is analyzed in samples containing up to 42.5 mol % of ZnO by standard and correlation solid-state nuclear magnetic resonance: (i) 1D 31P MAS-, DQ-SQ-, and the recently developed DRENAR-NMR sequences are used to describe the local order structure and to quantify the 31P/31P interactions, (ii) the Na+ ions distribution is analyzed by 1D 23Na MAS NMR and 23Na(31P) REDOR NMR experiments, and (iii) 67Zn static NMR experiments are recorded at very high field (21.1 T) to monitor the evolution of the Zn coordination state all along the composition line. Altogether, the set of data offers a detailed analysis of the glass network structure and clarifies the two-domain evolution of the glass transition temperature. While Co2+ doping has been used for decades to reduce the T1 nuclear relaxation times, only sparse information about the optimum CoO amount and i...
