    Synthesis and characterization of polypyrrole-platinum nanocomposite-coated latex particles

    Deposition of polypyrrole-platinum (PPy-Pt) nanocomposite from aqueous solution onto micrometer-sized polystyrene (PS) particles was conducted. The PS seed particles and resulting composite particles were exte...

    Cl Do** Effect by Thermal Treatment with KCl for ZnO Single Crystals

    We investigated the optical and electrical properties of ZnO single crystals coated with KCl by examining the photoluminescence (PL) at 9 K and the temperature dependence of the carrier concentration. The band...

    Lattice Vibrational Modes in 1222 Phase of Pb-Sr-La-Ln-Cu-O System (Ln; Gd, Dy, Ho, Er)

    Measurements of infrared absorption in insulating compounds of the 1222 phase of Pb-Sr-La-Ln-Cu-O system have been made. Lanthanoid (Ln) ions of Er, Ho, Dy and Gd have been used. Absorption peaks near 600 cm−1 an...
