​Quantum dots (QDs) refer to semiconductor nanoparticles with a size smaller than the Bohr radius of the exciton and exhibiting quantum confinement effects. Due to the quantum confinement effect, the fluorescence emission of quantum dots is related to their diameter and chemical composition. By compounding with semiconductor surfaces, their optical and photochemical properties can be enhanced. Traditional quantum dots are mostly composed of heavy metal elements. Although their excellent performance has been widely used in fields such as biological imaging, electrochemistry, and energy conversion, heavy metal elements can cause environmental pollution and affect the health of organisms.
