Abstract
A quantum dot alloy nanomaterial, a preparation method therefor, and a semiconductor device. The quantum dot alloy nanomaterial comprises N alloy nanostructured units arranged in sequence in a radial direction, wherein N is larger than or equal to 2. The alloy nanostructured units comprise type A1 and type A2. Type A1 or type A2 is a gradient alloy component structure in which energy level width increases or decreases from inside out in the radial direction, respectively. In quantum dot alloy nanomaterial, alloy nanostructured units of type A1 and type A2 are alternately distributed, and the energy levels of adjacent alloy nanostructured units are continuous. The quantum dot alloy nanomaterial not only achieves higher luminous efficiency, but satisfies comprehensive performance requirements of a QLED device and a corresponding display technology for quantum dot alloy nanomaterial, and is an ideal material applicable to QLED and display technology.
