Paper Abstract

Aqueous methods for nanomaterial synthesis are environmentally friendly, very versatile, inexpensive, and convenient for the processing of large scales of multi-component ceramics and semiconductors. Using these techniques, we have investigated the potential of developing methods for the production of multi-kilogram scale quantities of high quality, optical-grade ZnS nanomaterials. These nanomaterials are suitable for use in the creation of optical windows and components through sintering and pressing processes. The quality of the ZnS nanoparticles is achieved and maintained through the strict control of the reaction parameters and processing techniques. Currently, our processing techniques have been successful in lowering the impurity levels below 200 ppm. Drying and de-agglomeration techniques have also shown substantial improvements in the pressed density of the nanopowders, enabling their use in optical applications. Powder XRD patterns of the ZnS nanoparticles have shown the production of highly crystalline particles of pure cubic (zinc blende) structure.
