Abstract
Copper doped ZnS nanoparticles with different capping agents have been synthesized through chemical co-precipitation method. Polyvinylpyrrolidone (PVP), 1-thioglycerol and Trioctylphosphine oxide (TOPO) were used as capping agents. X-ray diffraction (XRD) studies revealed the average particle size of ZnS:Cu2+ with different capping agents to vary from 3 nm to 4 nm. Energy dispersive X-ray spectroscopy (EDAX) measurements confirmed the presence of Cu in the ZnS lattice. UV-Vis spectroscopy revealed blue shift for all the samples with respect to the bulk value. The band gap energy values were in the range of 4.29 eV to 4.86 eV. The blue shift was attributed to the quantum confinement effect. Room temperature photoluminescence (PL) spectrum of the ZnS:Cu2+ capped nanoparticles exhibited emission in the visible region with multiple peaks at an excitation wavelength of 250 nm
