Abstract
In this work, we report the structural and optical properties of synthesized Zinc Sulphide nanoparticles. Here we used zinc acetate and sodium sulphide as source materials in a high energy planetary ball mill at rotation speed of 300 rpm with ball to powder ratio 5:1 for 30-90 min. Powder samples were milled for 30, 60 and 90 min separately. The structural and optical properties of the prepared ZnS nanoparticles have been characterized by using X-ray diffraction, Field emission scanning electron microscope, Energy dispersive analysis of X-rays, UV-vis-NIR spectrophotometer and Fluorescence spectroscopy. The crystallite size of the synthesized ZnS nanoparticles is found to be in the range of 3-4 nm. FESEM morphology shows the needle type structure of ZnS samples. The value of optical band gap has been found to be in the range 3.76-3.84 eV. Room temperature photoluminescence spectrum of ZnS samples exhibit a blue emission peaked at 466 nm under UV excitation.
