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.
Claims17
A method for forming ternary Group III-V nanocrystals, the method comprising:
- dispersing binary Group III-V nanocrystals in a molten inorganic salt;
- adding an ion-exchange additive comprising a Group III element or a Group V element to the molten inorganic salt;
- heating the molten inorganic salt for a time and at a temperature at which the Group III element or the Group V element of the binary Group III-V nanocrystals and the Group III element or the Group V element of the ion-exchange additive undergo cation exchange to form the ternary Group III-V nanocrystals.
