Morphology and photophysical properties of polymer thin films dispersed with dye nanoparticle
چکیده انگلیسی

We prepared nanoparticles of an organic dye, acridine orange (AO), dispersed in poly(methacrylic acid) (PMA) films by spin-coating the solution of the two components. The surface of the AO/PMA films became bumpier with increasing AO concentration (cAO). The absorption and fluorescence spectra of AO/PMA films exhibited a marked dependence on cAO at low cAO (cAO < 2.1 × 10− 1 mol kg− 1), and were independent of cAO at high cAO (cAO > 2.1 × 10− 1 mol kg− 1). The peak shift of fluorescence spectra with changing cAO was as large as ∼ 100 nm.
