Anyone please suggest me as to how i increase the ph of quantum dot from pH 3 to pH 7 without adding any groups to it or if that group is added then further how should i purify it?
Thank you for your reply sir. The solvent is water and the QDs are of carbon. Suppose i want to add base such as NaOH to it but i dont want Na groups to get attached to it as the washing of QD is not possible. can you suggest any alternative.
I agree with Dr. Markus answer about adjusted you pH value, but how you knew that Na attached to the QDs, you can test that by EDS or RBS technique for compositional characterization.
