	Abstract

Formation of nanosized mixed semiconductor Pb_xCd_1-xS in situ into PEO–polymer electrolyte matrix at room temperature is reported. The disperse phase was identified by X-ray diffraction analysis. Optical microscopy shows the increase in amorphicity with dispersal of semiconductor while scanning electron microscope/transmission electron microscope affirmed the formation of nanoparticulates with various sizes. The size distribution was further supported by Ultraviolet/Visible absorption of the colloid. The detailed electrical characterizations show that the dispersed Pb_xCd_1-xS introduced a small (13%) electronic conductivity into pure ion conducting PEO:NH₄I polymer electrolyte matrix.
