Aqueous Synthesis and Characterization of TGA-capped CdSe Quantum Dots at Freezing Temperature

Aqueous Synthesis and Characterization of TGA-capped CdSe Quantum Dots at Freezing Temperature

CdSe quantum dots (QDs) have traditionally been synthesized in organic phase and then transferred to aqueous solution by functionalizing their surface with silica, polymers, short-chain thiol ligands, or phospholipid micelles. However, a drastic increase in the hydrodynamic size and biotoxicity of Q...
