To give recommendations on the composition of flexible hybrid polymer nanocomposites and their suspensions with optimized characteristics of their luminescent and piezoelectric response, suitable for use in light-emitting devices and to mobile non-destructive controling the surfaces of structural elements. popup.description2 Comprehensive studies, using various experimental, theoretical, and computational methods, of several oxide glasses, luminescent oxide micro/nano-sized crystals, suspensions, and solid forms of polymers have allowed us to identify their compositions that are most promising in the future for studying the composition, structure, and interactions that determine the formation of interphase layers in composites made based on these components. Engineering of such interphase layers can be used as an effective way to control the optical, in particular luminescent, properties of such composites. There are among those selected for further detailed studies: - - composites based on glass matrices of two types: M2O-Р2O5-B2O3-Bi2O3 and M2O-Р2O5-B2O3-Bi2O3-(Pr2O3), (M = Li, Na, K); - polymer matrices based on micro fibrillated cellulose; - luminescent oxide micro/nanocrystalline compounds: calcium aluminate, co-doped with Europium Eu2+ and Dysprosium Dy3, (CaAl2O4:Eu,Dy), strontium-calcium sulphate doped with manganese ions, Sr0,95Ca0,05(SO4):Mn; barium titanate doped with Europium or Praseodymium ions, BaTiO3:Eu / Pr.
