Abstract:

Colloidal semiconductor nanocrystals (quantum dots) have attracted great attention for their distinguished roles in fundamental studies and technical applications such as biological labeling and optoelectronic devices. In the last decade, the main efforts have been focused on the preparation of size-tunable binary or core-shell nanocrystals with different emission colors. In our research, we also focus on the development of highly luminescent composition-tunable quantum dots across the whole visible spectrum. The resulting high-quality size- and composition-tunable quantum dots have been successfully used as multicolor biological nanoprobes for imaging, sensing, and drug delivery applications.
