Abstract
A method of concentration profile measurement of luminescent ions by ion sputtering has been applied to detect the boundary between alkali ions of glass wafers, which were contacted anodically by acid solution, and succeeding hydrogen ions after the application of an electric field. The transport number of lithium ions was found to be unity. Mobilities at 25 and 50 °C agree with data obtained from conductivity measurements. From the conductivity change during transport the mobility of succeeding hydrogen ions is also evaluated.Keywords
