  • COLLOIDAL TERNARY GROUP III-V NANOCRYSTALS SYNTHESIZED IN MOLTEN SALTS
    Publication number: 20220127155
    Abstract: Methods of synthesizing colloidal ternary Group III-V nanocrystals are provided. Also provided are the colloidal ternary Group III-V nanocrystals made using the methods. In the methods, molten inorganic salts are used as high temperature solvents to carry out cation exchange reactions that convert binary nanocrystals into ternary nanocrystals.
    Type: Application

  • Colloids of inorganic nanocrystals in molten media and related methods
    Patent number: 11040323
    Abstract: Colloids comprising inorganic nanocrystals dispersed in a molten salt or a liquid metal are provided. The molten salt may comprise an ion which is a Lewis acid or a Lewis base in the presence of the inorganic nanocrystals. Solid composites formed from the colloids are also provided. Methods of using the colloids as media for inducing chemical transformations using the inorganic nanocrystals are also provided.
