• ZnS nanostructures were synthesized by simple wet chemical route and annealed at two different temperatures of 50°C and 180°C. From the measurements of transmission electron microscopy and contact-mode atomic force microscopy, it was found that annealed temperature changed the morphology from nanoparticles to nanorods. The optical properties of the synthesized ZnS nanomaterials were characterized by UV-visible absorption spectroscopy and photoluminescence spectroscopy. The structural and elemental analyses were carried out by powder X-ray diffraction pattern and energy dispersive X ray absorption spectroscopy, respectively. Absorption edge of the nanoparticles(295 nm)and nanorods(326 nm)were shifted towards shorter wavelength compared to bulk ZnS(337 nm)due to the quantum confinement effect.
