Structural Investigation of 95(0.6Li ₂ S0.4SiS ₂ )5Li ₄ SiO ₄ Oxysulfide Glass by Using X‐ray Photoelectron Spectroscopy

S2 p and O1 s photoelectron spectra were obtained for the 95(0.6Li 2 S0.4SiS 2 )5Li 4 SiO 4 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.
