Summary
Chalcogenide-based materials, including nanostructures, quantum dots, composites, and thin films, exhibit unique optical properties across the near- and mid-infrared spectral regions. Their strong infrared response, tunable band gaps, and compatibility with sensing and photonic platforms make them highly relevant for next-generation spectroscopic technologies.
This Special Issue aims to gather recent advances in the design, synthesis, characterization, and application of chalcogenide-based materials for infrared spectroscopy, optical sensing, and photonic technologies. Topics include the synthesis and functionalization of chalcogenide-based materials; their absorption, fluorescence, and nonlinear optical behaviour in the near- and mid-infrared regions; and their integration into spectroscopic and sensing platforms. Studies addressing applications in chemical, biological, biomedical, and environmental analysis are particularly encouraged.
This Special Issue welcomes original research articles and review papers focused on chalcogenide-based materials in infrared spectroscopy. Among the topics are:
· Chalcogenide-based nanostructures with near-infrared optical properties;
· Chalcogenide glasses, thin films, and hybrid materials for infrared spectroscopy;
· Absorption, fluorescence, and nonlinear optical properties in the NIR/MIR regions;
· Chalcogenide-based platforms for chemical, biological, and environmental sensing;
· Surface-enhanced infrared spectroscopy using chalcogenide nanomaterials;
· Structure–property relationships in chalcogenide optical materials.
