Solution processed chalcogenides

Chalcogenide glasses are well known for their various photo-induced phenomena and have drawn great interests for their unique optical properties. We characterize the optical and structural properties of amorphous chalcogenide materials synthesized using a low-temperature, non-vacuum method of depositing As-S and Ge-Sb-S from organic solutions.
