摘要：

Chalcogenide glasses show a unique potential for creating gradient refractive index (GRIN) lenses, which would reduce the size and weight of infrared thermal imaging system and remain/improve its performance. Here, we propose a new method that forms a GRIN chalcogenide glass-ceramics (GCs) by creating low refractive index (n) CsCl nanocrystals within a high n GeS2-Sb2S3 glass matrix. After specific gradient thermal treatment, the GRIN structure of Delta n similar to 0.04 was formed through the gradient precipitation of CsCl. This work would pave a new path to design the GRIN chalcogenide GCs through a selective crystallization of halide crystals with low n.
