  • Sn doped ZnS nanowires for white light source material
    Patent number: 10403495
    Abstract: According to exemplary embodiments, a method of synthesizing tin (Sn)-doped Zinc Sulfide (ZnS) nanostructures for electroluminescent white light source includes coating a substrate, including a silicon oxide layer, with Sn by vacuuming depositing Sn as catalyst nanostructures on the substrate, placing the substrate coated with Sn in a furnace, introducing a carrier flow gas into the furnace, adding a ZnS power to the furnace, growing ZnS nanostructures, and dissolving Sn in the growing ZnS nanostructures. The S vacancies are on a surface of the ZnS nanostructures. The ZnS nanostructures are grown on the substrate having a temperature in a range of 750° C. to 850° C.
    Type: Grant
