Аннотация: In this work, synthesis of spherical AgNPs and their influence on optical properties of highly fluorescent organic dye rhodamine 6G (R6G) and low fluorescent conjugated polymer (RZ11) was investigated. Fluorescence changes of R6G was studied in solutions when concentration of AgNPs was increasing and fluorescence changes of RZ11 conjugated polymer was studied in thin films when layer of AgNPs was presented. Absorption and fluorescence spectra, and fluorescence decay kinetics of solutions and thin films were recorded by using steady-state and time-resolved spectroscopy. Fluorescence decay kinetics revealed that no energy transfer occur in solutions of R6G (10-6 M) and AgNPs (2.5x10-4÷7.5x10-4 M). In thin films with conjugated polymer, quenching of fluorescence with AgNPs was detected because of the energy transfer from fluorophore to metal due to short distances.
