Cadmium sulfide nanoparticles were synthesized by using PEG, EDTA and PVP as capping agents by chemical co-precipitation technique at room temperature and as prepared samples were annealed at a temperature of 80 ºC. The powder X-ray diffraction (XRD) pattern revealed that CdS nanoparticles synthesized with PEG, EDTA and PVP as capping agents are in cubic phase with crystallite size in the range of 3-8 nm. From SEM images it was noticed that the nanoparticles with all capping agents are spherical in shape and agglomeration less in PEG capped nanoparticles. The EDAX spectrum confirms the presence of Cd and S atoms in samples with and without capping agents is in near stoichiometric ratio. Photoluminescence (PL) studies revealed emission at 490 nm and 620nm. For CdS without capping agent the peak intensity is less and then increases in the order of capping agents PEG, PVP and EDTA respectively. The chemical interaction and functional groups in CdS nanoparticles were identified by FTIR spectra. Strong interactions corresponding to the CdS nanoparticles were noticed from FTIR spectra. All samples with and without capping agents exhibited diamagnetism.
