Iranian researchers have succeeded in synthesizing zinc sulfide nanoparticles with a dimension of 21 nm through the hydrothermal method.
The product is a semi-conductor and can be used in optics, photo-electronics, sensors and catalysts,
"The main objective of this research is to synthesize zinc sulfide at the nanometric scale and optimize its synthesis by comparing temperatures and timing to determine the band gap of the products," she said.
"Size control is one of the most important parameters in the synthesis of semiconductors. However, the most important parameter is particle size distribution. In this research, nanoparticles were synthesized at 21 nm with appropriate size distribution."
Among various methods, the hydrothermal method is appropriate for the synthesis of nanoparticles due to its low cost, high performance and the ability to be used on a large scale. Among the advantages of this research, mention can be made of the use of simple initial material, appropriate temperature and time conditions, and simple laboratory facilities.
One of the results of the research was the application of hydrothermal method to synthesize zinc sulfide nanoparticles with a dimension of 21 nm. The product is an II-IV semiconductor with a direct band gap of 3.65-3.87 eV.
