Abstract: Quantum dots(QDs, also known as colloidal semiconductor nanocrystals) are new luminescent inorganic materials. Because of their particular structures, optical and electrical properties, QDs have shown potential applications in thin film light-emitting devices, non-linear optical devices, solar cells and life science. So far, highly luminescent QDs were synthesized by organic synthetic approach and aqueous synthetic approach. Compared to organic approach, the aqueous approach is simple, green and cheap, and as-prepared QDs are more preferable for their use in biomedical applications because they are water-soluble and exhibit good optical property and biocompatibility. In this review paper, we mainly introduced the aqueous synthetic approaches and some key bio-applications of luminescent QDs, and discussed future prospects.
