New Chalcogenide Glass-Ceramics Based on Ge-Zn-Se for IR Applications.

The consumer market requests infrared (IR) optical components, made of relatively abundant and environmentally friendly materials, to be integrated or attached to smartphones. For this purpose, three new chalcogenides samples, namely GeZnSe (d_GZSe-1), GeZnSe (d_GZSe-2) and BaGeZnSeI (d_GZSe-3) were obtained by mechanical alloying and processed by spark plasma sintering into dense bulk disks. Obtaining a completely amorphous and homogeneous material proved to be difficult.
