摘要

Chalcogenide glasses based on As_2S_3 have been studied extensively due to their optical and electronic properties and have been examined recently for use in optical waveguide components. Structural and chemical variations imposed by processing conditions (film deposition or fibre drawing) can lead to changes in linear and nonlinear optical properties as well as other physical properties. This paper reports our current results on x-ray photoelectron spectroscopy (XPS) studies of the resulting chemical composition at the film surface as compared to the parent bulk glass and the corresponding variation in the nature of chemical bonds and electronic structure. Special emphasis is focused on identification of bridging versus nonbridging sulphur atoms using XPS chemical shifts. Variations, where present, in surface chemistry due tot eh effect of x-ray exposure, sputtering and laser irradiation on bulk and thin film As_2S_3 samples are reported.
