Abstract
We investigate the direct incorporation of lead sulfide nanoplates PbSNP in poly34ethylenedioxythiophene PEDOT matrix without any additives The PbSNP was synthesized by using an ultrasonic assistance simple method and composite of them with PEDOT was carried out by a simple solidstate polymerization method The TEM images Xray diffraction patterns and absorption spectra confirm the incorporation of PbSNP in PEDOT matrix The XRD pattern showed that the prepared PbSNPs are crystalline in cubic rock salt structure with 8 nm average grain size The UV/Vis/NIR spectrum of PEDOT/PbSNP nanocomposite shows a characteristic peak at NIR region and a large blue shift rather than bulk lead sulfide This shift confirms synergetic effect between PEDOT matrix and PbSNPs and presence of quantum confinement effect for prepared PbSNP In addition this characteristic peak is very much dependent on the PbSNP concentration and can be used for design tunable NIR materials
