✦ Synopsis

Abstract

Poly[2‐methoxy‐5‐(2′‐ethyl‐hexyloxy)‐1,4‐phenylene vinylene] (MEH‐PPV) was grown on porous GaAs (π‐GaAs) by spin coating and studied via scanning electron microscopy (SEM) and room temperature photoluminescence (PL). The SEM investigation revealed that MEH‐PPV was grown deeply in the porous structure and had a filament‐like shape. The PL result showed that a strong quenching effect occurred when using π‐GaAs. This effect was suggested to be due to photoinduced charge transfer at the MEH‐PPV/GaAs nanocrystallite interface. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
