Abstract	Four perylene derivatives, including commercially available dyes Lumogen Red and Lumogen Orange, as well as 1,6,7,12-tetrachlоrоperylene-3,4,9,10-tetradicarboxydianhydride (Dye I) and 3,4:9,10-bis(1,2-benzimidazole)- 1,6,7,12-tetra(4-tert-octylphenoxy) perylene (syn/ anti-isomers) (Dye III, which was prepared from dye I through intermediate 3,4:9,10-bis(1,2-benzimidazole)-1,6,7,12-tetrachloro perylene (Dye II)) were used for preparation of polysiloxane samples (PSi) containing different concentrations of gold nanoparticles (GN). Dyes I and III demonstrate significant fluorescence intensity increase upon addition of GN independent on excitation energy. For Lumogen Red composition in PSi some increase of fluorescence intensity was observed upon addition of small concentrations of GN, while further increase of GN concentration quenches fluorescence. The increase of Lumogen Red emission intensity, which depends on energy of excitation, is probably due to the increase of radiation decay rate since excitation rate decreases. Effect of GN on Lumogen Orange provided quenching of fluorescence even at small concentrations of GN. Calculations at DFT level of approximation for dye III suggest location of GN in plane of perylene core for increase of fluorescence intensity.
