| Abstract Scope |
Chalcogenide glasses (ChGs) are used for their optical properties in the infrared spectrum. The optimization of crystal phases in Ge-As-Pb-Se (GAP-Se) glass can be done through heat treatments. Using differential scanning calorimetry (DSC) and X-ray diffraction (XRD), particular nucleation and growth temperatures for crystal growth are identified. This is done by analyzing a theoretical 0°C/min heating rate in the thermal analysis to identify the temperatures. By optimizing the high-index PbSe phase, we can spatially control the refractive index, making a gradient refractive index (GRIN) glass using laser writing. |
