**In present report the recent results on studies of structural properties of chalcogenides glasses (CG), and their application in holographic recording are reviewed. The changes of optical, thermal and other properties of chalcogenide glasses and functional materials structures on their base are connected with changing of the structure. XRD, EXAFS, AFM, SEM techniques and Raman spectroscopy...
Raman spectroscopy is a fast, sensitive, and non-destructive technique for exploring semiconductor nanocrystals fabricated by various methods. Selective probing of electronic and vibrational spectra of different parts of heterogeneous NCs such as core-shell systems by tuning the excitation wavelength in resonant Raman scattering is considered. The analysis of phonon spectra is applied for...
Compounds of ternary (I-III-VI) and quaternary (I-II-IV-VI) metal chalcogenide nanocrystals (NC) are promising materials for photodetectors and absorber layers of thin-film solar cells of the new (third) generation, fluorophores and low-toxic fluorescent labels for biomedical applications, photocatalytic devices, supercapacitors, and other energy conversion and storage devices. The advantages...
Materials with metal-to-insulator phase transition occurring under the external biasing have an unprecedented potential in control of electromagnetic radiation in a wide frequency range from microwaves to the visible. The focus of this talk is numerical demonstration of how the space of material parameters is connected with the space of functionality at far- and mid-infrared frequencies. The...
