Summary
Chalcogenide-based nanostructures are gaining increasing attention because their tunable electronic structure, strong light-matter interaction, and composition-dependent defect chemistry enable relevant responses in optical spectroscopy, optoelectronics, and photocatalysis. Sulfides, selenides, tellurides, and related heterostructures offer versatile platforms for controlling optical absorption, charge transport, surface reactivity, and photoinduced functionality.
This Special Issue aims to collect high-quality experimental and theoretical studies on the synthesis, characterization, modeling, and functional application of chalcogenide-based nanostructures. The scope includes nanoparticles, thin films, quantum dots, low-dimensional materials, composites, and heterostructures, with emphasis on structure-property relationships, spectroscopic response, optoelectronic behavior, and photocatalytic performance.
Suggested themes include:
· Green and chemical synthesis of chalcogenide nanostructures.
· Raman, SERS, UV-Vis, infrared, and photoluminescence spectroscopy.
· DFT and theoretical modeling of electronic and optical properties.
· Chalcogenide thin films, quantum dots, and heterostructures.
· Optoelectronic, photonic, and sensing applications.
· Photocatalytic and environmental applications.
