"\"The proposed project is designed as a basic, predominantly experimental study focused on investigation and utilization of surface-enhanced optical phenomena on metal, mostly gold or silver nanoparticles embedded in a polymer matrix, with a strong spatial localization of the enhancement effects. This enhancement is expected to lead to a localized decrease of the excitation light intensity threshold needed to induce the optical response of the active molecules, showing possible applications in the design of active components with density of active pixels far above the limits of traditional photolithographic methods. For this purpose, novel functional photochromic and fluorescent organic molecular and polymer materials will be synthesized with molecular units enabling their anchoring to the metal nanoparticle surface. Photochromism and luminescence of these materials in \"\"hot spots\"\" generated by optical fields on metal nanostructures in polymer nanocomposites will be investigated.\""@en .
