Synthesis of Zinc Sulfide Nanopowder by Chemical Method and purifying it to improve the optical properties

Semiconductor nanoparticles, have different properties in comparison to their bulk particles due to their small dimensional quantum effects. So they have different and special electrical and optical properties. Controlling the synthesized particles size and reducing particle size due to increased energy gap and optimizing the physical and chemical properties is very effective. So one of the most important research areas in the world is producing semiconductor nanoparticles with controlld size. It was also found that the purity of the used materials have high influence on optical properties of sintered parts. As a result, selecting the appropriate method for the processing of optical material with high purity is very important. In this research by choosing the appropriate method, ZnS nanopowder is synthesized and produced with a specific process and then purified to improve the optical properties.
