Alkali depletion and ion-beam mixing in glasses

PDF Version Also Available for Download.

Description

Ion-implantation-induced alkali depletion in simple alkali-silicate glasses (12M/sub 2/O.88SiO/sub 2/) has been studied for implantations at room temperature and near 77K. Results are consistent with a mechanism for alkali removal, by heavy ion bombardment, based on radiation-enhanced migration and preferential removal of alkali from the outermost layers. Similar results were obtained for mixed-alkali glasses ((12-x)Cs/sub 2/.O.xM/sub 2/O.88SiO/sub 2/) where, in addition, a mixed-alkali effect may also be operative. Some preliminary experiments with ion implantation through thin Al films on SiO/sub 2/ glass and on a phosphate glass show that inter-diffusion takes place and suggest that this ion-mixing technique may be ... continued below
