摘要：
Cyclohexylamine-N-dithiocarbamate ligand was prepared and used to synthesize Cu complex [Cu (S2CNC6H12)(2)]. The effect of capping molecule was studied through the thermolysis of the precursor in hexadecylamine (HDA) and tri-octylphosphine-n-oxide (TOPO) to give HDA and TOPO-capped CuS nanoparticles by varying their concentrations. The absorption spectra showed localized surface plasmon resonances (LSPR) and quantum confinement effect for all samples. TEM micrographs displayed welldispersed isotropic particles for the sample prepared at higher concentration of HDA and anisotropic particles for the sample prepared at lower concentration which was different with TOPO capped nanoparticles. The synthesized copper sulfide nanoparticles revealed hexagonal phase. (C) 2017 Elsevier B.V. All rights reserved.
