Abstrakt: A thio Schiff base ligand, 1-benzylidenethiourea (L), was used as sulfur source and capping agent together for preparation of CdS nanostructures via solvothermal method in glycerol solvent. The Schiff base was characterized by elemental analysis as well as FT-IR and 1H, 13CNMR spectroscopies. Structure characterization of obtained CdS nanoparticles were studied by XRD, EDX, FT-IR and UV-Vis spectroscopies. SEM and TEM images were showed that the synthesized CdS have flower-like structures contain of several nanorods. The optical properties of the product was characterized by photoluminescence (PL) spectroscopy measurements. The PL spectrum of CdS nanoparticles shows a blue visible spectrum. The ultraviolet absorption spectrum shows the blue shift in the band gap due to the quantum confinement effect. The effect of some parameter such as solvent type, temperature and duration of reaction on size and morphology of CdS nanostructure was investigated as well. [ABSTRACT FROM AUTHOR]
