Abstract
A quantum dot and its preparation method and application. The method includes the steps of forming a compound quantum dot core first, then adding a precursor of a metal element Mto be alloyed into the reaction system containing the compound quantum dot core. The metal element Mundergoes cation exchange with a metal element Min the existing compound quantum dot core, thereby forming a quantum dot with an alloy core. In this method, the distribution of alloyed components is not only adjusted by changing the feeding ratio of the metal elements and the non-metal elements, but also by a more real-time, more direct, and more precise adjustments through various reaction condition parameters of the actual reaction process, thereby achieving a more precise composition and energy level distribution control for alloyed quantum dots.
