Abstract:
A multi-emission quantum dot includes a first core having a first thickness along an axis from a first surface to a second surface of the first core, a first shell enclosing the first core, a second core surrounding the first shell. The second core may has a second thickness along the same axis smaller than the first thickness. The quantum dot also includes a second shell enclosing the second core. The first core may be configured to emit light of a first color, and the second core may be configured to emit light of a second color different from the first color.
