AbstractThe spectroscopy and fluorescence lifetime of poly [2-methoxy-5-(2'-ethylhexoxy)-p-phenylene vinylene] (MEH-PPV) in mixtures of a poor solvent (cyclohexane or methanol) and a good solvent (chloroform) have been studied. With an increasing proportion of the poor solvent, the absorption, excitation and emission spectra change significantly when the poor solvent proportion is above a critical value. A new component is formed with spectra (absorption, excitation and fluorescence) at longer wavelength (lower energy). Fluorescence decay in different solvents has been measured and the new component has a longer lifetime compared with that in chloroform. All the results illustrate that a new emission center (emitter) is formed when the mixed solvent of MEH-PPV contains a higher proportion of the poor solvent. (C) 2002 Elsevier Science B.V.
