Preparation and characterization of luminescent-electric composites based on nanophosphors doped with Ln(III) ions abd carbon nanostructures

Konrad Kubasiewicz

Abstract

The presented thesis is concerning research on the new composite materials doped with lanthanide ions. The main aim was to design, to fabricate and to characterize the innovate composite materials based on inorganic nanoluminophors doped with Ln3+ ions, as well as based on carbon nanostructures. The new materials obtained exhibit both electrochemical and luminescent properties. The project was focused on chemical formulas, concentration ratios of components, mechanical and physicochemical properties, necessary additives, method of fabrication and other aspects of materials engineering. The fabrication process included chemical synthesis of components and homogenisation (or dispersion) in proper ratios to obtain composite materials. The characterization of products was focused on structural (SEM, TEM, XRD, FT-IR), luminescent (excitation and emission spectra, luminescence decay, CIE indexes) and electrochemical (CV, EIS) properties. Obviously, the mechanical properties were also concerned, however without a quantitative assessment.
