Abstract
The present disclosure provides a yellow-red spectral quantum dot, a synthesis method therefor and application thereof. The yellow-red spectral quantum dot has an alloyed structure of CdSe@CdZnSe/CdZnS or an alloyed structure of CdSe@CdZnSe/CdZnS/ZnS, the ZnS shell being one or more monolayers, and the fluorescence emission peak wavelength of the yellow-red spectral quantum dot being between 580 nm and 640 nm.
