Abstract

Nanocomposites of conducting polyaniline with ZnS:Mn nanoparticle (PAni/ZnS:Mn) have been synthesised by chemical co-precipitation method. The weight percentage of ZnS:Mn varied from 1 to 28%. PAni/ZnS:Mnnanocomposites has been synthesised by adding the ZnS:Mn precipitate in to the prepared Polyaniline solution. The Structural and morphological properties have been studied by X-ray diffraction and Field Emission scanning electron microscopy. Optical characterization has been done by UV-Vis and Photoluminescence. From XRD pattern prominent peak of PAni as well as ZnS:Mn are observed. Using Schrrer formula the particle size of ZnS: Mn was also calculated. FESEM image shows uniform distribution of ZnS:Mn on PAni matrix. UV-Vis graph of PAni/ZnS:Mnnanocomposites shows three peaks in common at ~250 nm, and broad peaks at ~300 – 350 nm and ~400 – 450 nm. From UV-Vis graph it is observed that the composites peak got blue shifted compared to ZnS:Mn. Photoluminescence emission of PAni/ZnS:Mn shows 5 peaks at ~273 nm, ~308 nm, ~400 nm, ~464 nm and ~484 nm. From the PL spectra it is also observed that as the ZnS:Mn concentration increases in the composites there is a shift of peak position compared to ZnS:Mn.
