ABSTRACT:
A semiconductor nanocrystal complex that is stable and has high luminescent quantum yield. The semiconductor nanocrystal complex has a semiconductor nanocrystal core of a III-V semiconductor nanocrystal material. A method of making a semiconductor nanocrystal complex is also provided. The method includes synthesizing a semiconductor nanocrystal core of a III-V semiconductor nanocrystal material, and forming a metal layer on the semiconductor nanocrystal core after synthesis of the semiconductor nanocrystal core.
