Influence of Fe on microhardness and dissolution rate of SbSI chalcogenide glass matrix

Abstract

© 2019 National Institute of Optoelectronics. All rights reserved. This paper presents the investigation of chemical stability and microhardness of ferroelectric glasses Sb-S-I doped with iron. We have investigated the influence of iron atoms introduced into the glass matrix, as well as other factors causing the change of chemical stability. The temperature measurements allowed us to determine the activation energies that define the solubility rate on the certain temperature. Increasing the doping level of iron atoms appears to decrease the chemical stability of the system. The mechanical measurements showed that the iron atoms increase Vickers microhardness of the system confirming their important role in the reinforcing the glass matrix.
