  目:CdSe Magic-Sized Nuclei, Magic-Sized Nanoclusters and Regular Nanocrystals: Monomer Effects on Nucleation and Growth
  要:
Following my previous presentation on “Targeted Cellular Imaging of Pancreatic Cancer via Single-Domain Antibody Bioconjugated Near-IR CdTeSe Quantum Dots”, I will discuss CdSe colloidal nanocrystals, as a model system, for the fundamental understanding of the formation of regular and magic-sized nanocrystals. I will address several debating topics in the present quantum dot area including the formation mechanism of monomers. Next, I will introduce recent advances in our labs in the synthesis of colloidal CdSe magic-sized nuclei (MSN) exhibiting sharp bandgap emission. I will introduce a model proposed to illustrate the nature of monomers and their degree of supersaturation (DS) affecting the formation of various CdSe MSN, magic-sized nanoclusters (MSCs), and regular nanocrystals (RNCs). Also, I will use tbt365可靠吗his model to address tuning the CdSe RNCs and/or MSCs into the CdSe MSN with the presence of acetate salts such as Cd(OAc)2 affecting the nature of the monomers. Such a discussion should bring insight into nucleation/growth of both regular and magic-sized nanocrystals for better quality control.
