Are your quantum dots capped with some organic capping agent? The first thing that comes to mind is centrifugation.

Gyoung Gug Jang

Once it was capped with organic molecules, you can try to inorganic ligand exchange in non-polar organic solvent and separate them with centrifuge.

Ranjit De

Quantum dots are not capped. These are doped. Please suggest me how to go ahead elaborately and also suggest some papers. Thank you once again.
