Optical properties of CO2+-doped ZNS nanoparticles synthesized using reverse micelle method
Rahizana Mohd Ibrahim1, Masturah Markom2, Kamal Firdausi Abd Razak3.
Zinc sulfide is a luminescence materials with important application that exist either as a
bulk material or in the form of nano crystal. Doped ZnS nanoparticles form a new class of
luminescence materials and provide a new physics to control the particles size. This paper
concerns detailed structural, spectroscopic and crystal field studies of ZnS nanoparticles,
both pure and doped with CO2+ ions that successfully synthesized at room temperature.
Zn1-xCoxS (x =0.00,0.02,0.04,0.06,0.08 and 0.10) was prepared by reverse micelle method
using sodium bis(2-ethylhexyl) sulfosuccinate (AOT) as surfactant. The effect of ion doping
on the optical characterization, structure and morphology of ZnS:Co2+ were investigated
using ultraviolet-visible (UV-vis) spectroscopy, photoluminesence (PL) spectroscopy, X-ray
diffraction (XRD), field-emission scanning electron microscopy (FESEM) and transmission
electron microscopy (TEM). EDAX spectra confirmed the incorporation of ion dopants
into ZnS crystal structure, and XRD results showed that ZnS:Co2+ nanoparticles crystallized
in a zinc blende structure. The particle size of all of samples ranged from 2 nm to 3 nm. In
the PL emision, two peaks were observed at 460 and 608nm that a new peak for Co2+
doped ZnS ever reported. The Co2+ doped ZnS nanoparticles using reverse micelle
method showed that there is considerable change in the photoluminescence spectra of
the ZnS nanoparticle doped Co2+.
