Abstract
In this work, we have synthesized Ag-Graphene Nanocompostie (AGN) by a simple method under mild condition. Further, Composites of poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) participated by AGN have been studied. The interaction and photoluminescence quenching of MEH-PPV/AGN composites have been observed using UV-visible and fluorescence spectroscopy. Based on UV-visible spectrum of different concentration of AGN blending with MEH-PPV, the absorption range was markedly enlarged, indicating the formation of ground-state charge-transfer complex (CTC). Besides, photoluminescence (PL) spectra of the MEH-PPV/AGN nanocomposite show an efficient PL quenching effect. Both of these results indicate that AGN could apply in photovoltaic device as an acceptor material.
