Preparation of UV-laser absorbing TiO2 masked on CdS conducting nanocomposites based on polyaniline

Herein, we report results of the studies relating to the preparation, structural, optical and electrical properties of polyaniline (PANI), nanocrystalline CdS, TiO2-masked-CdS and CdS/TiO2/PANI nanocomposites. The composites of polyaniline with different CdS/TiO2 contents were prepared via in situ polymerization, in presence of dodecylbenzene sulphonic acid (DBSA) as a functionalized protonic acid in water medium. The spectroscopic characterization of the resulting products were examined by XRD, UV-visible absorption, PL spectroscopy and conductivity investigated using four point probe
