| Abstract: | S2 p and O1 s photoelectron spectra were obtained for the 95(0.6Li2S0.4SiS2)5Li4SiO4 oxysulfide glass prepared by twin-roller quenching. A four-peak deconvolution technique was used to separate the S2 p peak of the glass into the components of bridging and nonbridging sulfur atoms. As a result of the deconvolution of the S2 p peak, we found that ∼92% of the sulfur atoms were present as nonbridging atoms. The O1 s peak of the glass was separated into two components: bridging and nonbridging oxygen atoms. This separation of the O1 s peak indicated that ∼85% of the oxygen atoms were present as bridging oxygen atoms. |
