Project ANCD 20.80009.5007.14 Multifunctional hybrid nanocomposites of different architecture from polymers and non- crystalline semiconductors for applications in optoelectronics,photonics and biomedicine

Type :Project within the State Programs funded by the National Agency for Research and Development of the Republic of Moldova
Head :Mihail Iovu, Dr.Sci., prof.
Duration :2020 - 2023
Division(s) :Laboratory of Optoelectronics “Andrei Andriesh”

Polymer-based nanocomposite materials, and non-crystalline multinary semiconductors are of great interest both from the point of view of fundamental and applied science, due to the potential use in high-tech fields, the possibility of simple processing and modification of the structurel units or morphology by laser, plasma or radiation techniques. The major objective of the project is to generate new knowledge and technologies on multifunctional hybrid nanocomposites of different architecture from polymers and non-crystalline semiconductors for priority areas in optoelectronics, photonics and biomedicine. The proposed topics include elaboration and synthesis of advanced materials and preparation of multilayer planar structures, of diffraction elements by holographic methods or by electron beam iradiation, of planar- or fiber optic nanostructured advanced sensors for environment and biomedicine, as well as of photoluminescent and electroluminescent elements with high efficiency. The project targets coordinating compounds with rare earth ions, bionanocomposites, as well as nanonocomposites based on multifunctional non-crystalline semiconductors. For the characterization of the new materials and structures, optical spectroscopy methods will be used (UV-VIS, IR, Raman, photoluminescence), as well as the technique of SEM and AFM microscopy, etc. The photo- and electron-induced phenomena, as well as the phenomena of electric charge transport will be studied. The project includes development of theoretical models, analysis and interpretation of the obtained experimental data. Attention will be paid to the study and theoretical modeling of the influence of the external fields on optical and kinetic characteristics of the various nanostructures, and nanocomposites. Nanoclusters of the "core-shell" type will be studied, with applications in biomedicine, including biomarkers, as well as multifunctional hybrid materials for cell engineering. The biocomposites, to which cytochrome c and cardiolipin complexes are attributed, will be modeled taking into account the experimental data of the kinetics of the reaction of the lipid peroxidation process. Based on the nanocomposite materials and obtained nanostructures the project aims to develop advanced devices for optoelectronics, photonics and biomedicine: diffractional structures, thin-film or nanostructured fiber-optic advanced sensors (for example based on SERS effect, plasmonic resonance, etc.), high efficiency photoluminescence and electroluminescence-based elements.
