Quantum dots are semiconductor nanocrystals with physical dimensions smaller than the exciton Bohr radius.

量子点是指半径小于或接近于激子玻尔半径的半导体纳米晶粒。

Quantum dots are a kind of semiconductor nanopaticles with the radius equal to or less than the exciton Bohr radius. They have tremendous potential in the field of biology and medicine because of their unique and tunable optical properties (broad excitation spectrum, narrow emission spectrum, precise tunability of their emission peak and negligible bleaching, etc) as new fluoresent probes.
