Interaction of structural phases, processes of formation and controlled control of the composition of optical centers, channels of dissipation of excitation energy and transfer of charges in hybrid oxide-carbon nanostructured composites. Subject of study. The role of mechanisms of physical interaction of phases and interfaces in hybrid oxide-carbon nanostructured composites in the formation of their mechanical, optical, and photoluminescent characteristics. The goal of the project was to find out at the atomic-molecular level the mechanisms of the interaction of components and the role of transition layers in determining the mechanical, optical, thermal and electrical conductivity characteristics of nanoparticles with oxide and carbon fillers. ocomposites based on glass and nanocellulose matrices with oxide and carbon fillers. The main hypothesis of the project assumed that intermediate (interphase) layers can be formed in oxide composites between the components, the structure and chemistry of which will undergo significant changes compared to the structure of the original compounds - components of the composites. This hypothesis was confirmed by the results of experimental and theoretically calculated studies. Systems made on the basis of glass samples and luminescent oxides of 5 types were studied. 1) Glass: nM2O-kB2O3xV2O5, where M = Na, K, Li; nK2O-mP2O5-kB2O3-(ZnO/PbO); nK2O-mP2O5-pMoO3-xBi2O3; nK2O-mP2O5-pWO3-x(V/Bi)-oxide. 2) Micro/nanocrystals: KBi(MoO4)2:Eu3+/Pr3+; K2Eu(PO4)(WO4); K3Tb(PO4)2:Eu; LaVO4:Eu3+, LaVO4:Sm3+, LaVO4:(Eu, Ca), LaVO4:(Eu, Er, Ca); K/NaCa(BO3):Eu3+. Comparison of experimental data (XRD, derivatography, calorimetry, electron, atomic force and optical microscopy, Raman, absorption infrared, luminescence spectroscopy) and computational studies (DFT, MD, TLM) ensured the reliability of the results and the validity of the conclusions drawn.  Product Description popup.authors Borysiuk Viktor I.
