Abstract
A quantum dot for emitting light under electrical stimulation has a center of a first composition and a surface of a second composition. The second composition is different than the first composition. An intermediate region extends between the center and surface and has a continuous composition gradient between the center and the surface. The quantum dot is synthesized in a one pot method by controlling the rate and extent of a reaction by controlling the following parameters: (i) type and quantity of reactant, (ii) reaction time, and (iii) reaction temperature.
