Preparation and characterization of CdS and CdS/polyacrylonitrile nanocomposites by γ-irradiation and emulsion polymerization

Authors


Abstract

CdS and CdS/polyacrylonitrile (PAN) nanocomposites were prepared by γ-irradiation and emulsion polymerization. The CdS and CdS/PAN nanocomposites were characterized by powder X-ray diffraction, infrared spectroscopy, Fourier transform Raman spectroscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and thermal analysis (thermogravimetric analysis/dynamic thermal analysis). In photoluminescence spectroscopy analysis, the maximum peak of CdS/PAN nanocomposites prepared by γ-irradiation and emulsion polymerization was at about 485 nm, whereas the maximum peak of CdS nanocomposites was at about 460 nm. © 2003 Wiley Periodicals, Inc.
