Abstract

This paper presents the experimental results of a study of how temperature affects the luminescence of molecular clusters of silver in photothermorefractive glasses. It is shown that, after the glasses are UV-irradiated in the absorption band of cerium ions, intense and broad-band luminescence appears in the visible region. The luminescence centers responsible for this luminescence are neutral silver atoms and neutral molecular clusters of silver. Heat treatment at 350°C causes a tenfold increase of the luminescence intensity. The luminescence intensity decreases by a factor of 10 as the sample’s temperature is increased from 25°C to 200°C. The temperature dependence of the normalized luminescence intensity is shown for a fiber with silver introduced by ion exchange.
