摘要：
A series of glass samples of composition [(x)MnF2-(x-80)NaPO3-(20)ZnF2] where x = 0, 10, 20, 30 and 40, has been prepared. IR and NMR spectroscopy have been performed, especially F-19 MAS and P-31 MAS NMR. On the basis of these measurements, glass structure may be described as a hybrid network of ZnF6 and MnF6 octahedra sharing corners and edges and also connected to tetrahedral fluorophosphate groups (PX)(4) where X = O- or F-. Sodium cations fill vacancies of this network. (C) 2015 Elsevier B.V. All rights reserved.
