I have been to a number of conferences where they discuss their seeding process. .chemists are doing the work during different steps of the process. ..fully automated would be pressing a button and walking away then coming back with a finished product...The shelling process is an entirely different process again as well as making the precursor. ..

This method is generally limited to producing small quantities of QDs because the time required to inject large volumes of precursors is too long for fast nucleation . Hot-injection methods on large scales typically result in an inhomogeneous particle size distribution.
Single-source precursor methods employ a molecular cluster compound containing all of the elements to be incorporated into the nanoparticle material, which decomposes at high temperature to initiate nanoparticle formation. One of the drawbacks of this method, however, is that the nanoparticle stoichiometry is inherently determined by the composition of the cluster compound. Other strategies to synthesize colloidal quantum dots include heating up precursors in solution, with the addition of other reagents during the course of the reaction.
