报告内容简述

   There are very few materials which are transparent in the 8-12 μm region and which are environmentally stable enough for practical applications. Chalcogenide glasses are glasses based on sulfur, selenium and tellurium. They have been intensively studied mainly due to its large optical transmission window from visible to infrared. Chalcogenide glass ceramics are composite materials containing glass and crystals with significantly improved mechanic, optical properties and photoelectric properties.

The preparation and properties of these materials with potential application for thermal imaging, solar energy conversion and energy storage will be presented.
