Abstract

Abstract Thermally stimulated depolarization currents and some spectrophotometric characteristics were measured for soda lime silicate glass in as received state and after exchange with ionic silver. Both, the effectiveness of the exchange and the form of silver within the glass framework, were modified by thermal treatment of the exchanged specimens. It has been shown that some of the bands recorded by TSDC technique are related with electrical polarization phenomena. The origin of these polarizations has been ascribed to more or less localized motion of sodium ions which in the near-surface layers of specimens became disturbed by various silver species.
