Abstract
A quantum dot (QD) composite material includes at least two structural units arranged sequentially along a radial direction. The at least two structural units include a type A1 structural unit and a type A2 structural unit. The type A1 QD structural unit has a gradient alloy composition structure with an energy level width increasing along the radial direction toward a surface, and the type A2 QD structural unit has a gradient alloy composition structure with the energy level width decreasing along the radial direction toward the surface. The two types of QD structural units are arranged alternately along the radial direction, and the energy levels in adjacent QD structural units having gradient alloy composition structures are continuous.
