Tuning of dielectric properties in Se78Te20Sn2 glass using UV–Vis-IR lasers
Source abstract
Abstract
Abstract Laser-induced phenomena in Chalcogenide Glasses (ChGs) are the issues of the systematic investigations with a view of better perceptive of the mechanism behind such effects as well as its practical applications. In fact, the study of the photo-induced effects in ChGs is still an on-going research activity. The present paper reveals the observation of photo-induced dielectric effects in ternary Se78Te20Sn2 (STS) ChG. We have developed a novel method to achieve a distinctive photo-induced effect in a second generation ChG by employing cw-laser sources of four different wavelengths. Our results show the demonstration of photo-dielectric effects in electrical properties (dielectric constant/loss and a. c. conductivity) of ternary STS ChG. A tentative explanation is also proposed for the observed effects.
