Abstract
A quantum dot composition, including a first quantum dot and a second quantum dot, wherein a valence band maximum energy level of the first quantum dot is different from a valence band maximum energy level of the second quantum dot, as determined by ambient photoelectron spectroscopy, and an energy band gap of the first quantum dot is identical to an energy band gap of the second quantum dot, as determined by ultraviolet-visible spectroscopy.
