| contents | Photoluminescence of MEH-PPV/PS Blends V. Gonçalves Débora T. Balogh A. Marletta Física, Astronomía y Matemáticas In this work we studied the optical properties of poly[2-methoxy-5-(2-ethylhexyloxy)-p-phenylene vinylene](MEH-PPV) using polymeric blends with polystyrene (PS). The photoluminescence (PL) spectrum of MEHPPVpresent three characteristic peaks correlating to aggregate electronic transition at 608, 674 and 742 nm at10K. An addition of PS in MEH-PPV films induces a red shift in the absorption spectrum and the PL spectrumpresents a new peak at high energy centred at about 572 nm at 10K. It is attributed to intra band transitionbetween localized intraband states. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434447 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.34 |
