| he local environment and spatial distribution of alkali ions in glasses is a subject of great fundamental and technological interest. To elucidate the alkali ion distribution, new experimental nuclear magnetic resonance (NMR) approaches are explored and applied to both single and mixed alkali glasses. These techniques rely on probing the distance dependent dipolar couplings among magnetic nuclei. Approaches studied and implemented include ;In the limit of short evolution times ;The distribution of sodium and lithium cations in various mixed alkali glass systems was studied by employing... |
