Cr doped ZnS nanorods with formula Zn1-xCrxS (x = 0.00, 0.08 and 0.10) were synthesized by co-precipitation method. All samples exhibits cubic structure, confirmed from X-ray diffraction data. Using Debye-Scherrer's formula, grain size estimated and indicating that samples define quantum confinement effect (QCE), which means that as prepared samples exhibits quantum dot. Chemical compositions of all samples were confirmed by energy dispersive spectra (EDS). Cr3+ ions doping has significant influence on the optical properties of ZnS nanorods. UV-Vis absorption study exhibited the presence of red shift for Cr doped ZnS compare to undoped. TEM study revealed nanorods for 8 at% and 10 at% Cr concentrations.
