Nano Elements Source, LLC, a biotech startup has licensed the NanoFermentation technology from Oak Ridge National Laboratory to further commercialize low cost, cadmium free photoluminescent nanoparticles produced using affordable, environmentally-friendly. This project aimed to develop post chemical processing of biosynthesized ZnS quantum dots (QD) to improve their efficiency of luminescence to make them suitable for solid state lighting applications. Several post processing approached were proposed and tested using to biosynthesized of ZnS QD. Optical properties of ZnS nanoparticles including soft chemical etching, and photonic etching have been tested and quantified against standard materials. We applied the developed chemical modification approach to control quality of chemically synthetized ZnS QD’s, and to calculate the maximum achievable efficiency of photoluminescence. We estimated the cost of the proposed post-processing treatment of nanoFermented nanoparticles and proposed several approaches to further the development of low cost nanoparticles for electro-optical and other applications relevant to DOE mission.
