Ternary Semiconductor Nanoparticles Embedded in PEO—Polymer Electrolyte Matrix

Abstract

Formation of nanosized mixed semiconductor PbxCd1 —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 PbxCd1—xS introduced a small (≤13%) electronic conductivity into pure ion conducting PEO:NH4I polymer electrolyte matrix.
