摘要: Abstract We report a facile synthesis of silver nanoparticles-graphene oxide (AgNPs-GO) nanocomposites and their interactions with Pyronin Y (PyY) molecules studied by UV-Vis absorption, steady-state time-resolved fluorescence spectroscopy techniques in aqueous solution. With this aim, firstly, monodisperse AgNPs two different sizes (4 6 nm) were synthesized using surfactant-assisted organic solution phase protocol comprising the consecutive thermal decomposition reduction (I) acetate. Secondly, anchored into GO nanoflakes via liquid self-assembly method to prepare AgNPs-GO nanocomposites. The morphology structure both colloidal characterized transmission electron microscopy (TEM), scanning (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) absorption spectroscopy. Finally, interacted PyY photophysical properties (steady-state time-resolved) techniques. spectroscopic results revealed that dye dramatically changed after its interaction
