Abstract
A method for producing quantum dots. The method includes cleaning an oxide substrate and separately cleaning a metal source. The substrate is then heated and exposed to the source in an oxygen environment. This causes metal oxide quantum dots to form on the surface of the substrate.
Claims4
A method for producing metal oxide quantum dots, the method comprising:
- a) cleaning an oxide substrate comprised of α-Cr2O3;
- b) cleaning a source comprised of a metal;
- c) heating the substrate;
- and
- d) exposing the substrate to the source in an oxygen environment causing metal oxide quantum dots to form on the surface of the substrate.
