Abstract

Chalcogenide and chalcohalide glasses were prepared and the resulting glass Tg's and spectra were investigated. Some chalcogenide glasses were prepared from thermally and chemically pretreated raw materials. Pretreatment steps produced a reduction in impurity absorptions caused by oxygen bonding to the constituent elements. Additions of small amounts of iodine improved attenuations by acting as a hydrogen getter material which eliminated H-Se absorptions. Due to low transition temperatures, chalcohalide glasses containing iodine may not meet commercial requirements.
