Cadmium sulphide nanoparticles have been obtained by using a quaternary 'water-in-oil' microemulsion. The nanoparticles properties have been investigated by absorption spectroscopy, photoluminescence (PL), and high resolution transmission electron microscopy (HR-TEM). With the aim of obtaining electro-optical devices, layered and blended heterostructures based on CdS quantum dots and a novel poli (2,5-dialcoxy-1,4-phenylenevinylene) with a 2,5 -O-(CH2)(12)- bridge (BDA-PPV), have been deposited on indium tin oxide (ITO) substrates. The film morphology has been measured by atomic force microscopy (AFM). The devices have been tested by current-voltage measurements after Al cathodes deposition on the top of the structure. The results have been related to the film morphology. (C) 2000 Elsevier Science S.A. All rights reserved.
