Inorganic semiconductor materials in nano-dimension have drawn intense attention in recent years because of their size-tunable optoelectronic properties arising from the quantum confinement effect. These materials often require to be incorporated into other materials, often polymers, to acquire necessary processability to the various shape and preservation of the quantum confinement effect. One of the most frequent forms of incorporation is the polymer/semiconductor nanocomposites. This paper describes the templated based synthesis of 5 nm CdSe nanoparticles (NEP) embedded polypyrrole nanorods. The electrochemical deposition (ECD) to the AAO membrane was used to construct the NEP-rod. In order to preserve quantum confinement effect of CdSe-NEP in the polypyrrole nanorods, distribution and total population of the particles were carefully controlled by concentration of the particle and monomeric pyrrole and electrodepostion parameters including current density and applied potentials. The transmission electron microscope and near-field scanning fluorescence microscopic measurement showed that NEP are homogeneously dispersed in the polypyrrole nanorod with diameters and length of 200 ~ 320 nm and 1 5 m respectively. This structure can be applied in the applications of solar cell, light-emitting diode, and sensors.
