Type: conference-paper
Abstract: In this work, the optical bandgap variations of the chalcogenide glass Ge15Se70Te5Sb10 in bulk, thin film, and nanocolloid form were explored. The bulk glass was synthesized through a conventional melt quenching method, while the thin film was produced by thermal evaporation, and the nanocolloid was obtained through solution-processed techniques. Optical bandgap measurements for each form, performed via UV-VIS-NIR spectroscopy, revealed a notable blue shift in the bandgap when transitioning from bulk to film and then to nanocolloid. The shift in optical band gap with dimensionality of the material underscores the tunable nature of the bandgap in chalcogenide glasses, presenting potential applications in photonic devices.
