TīmeklisThe current approaches to synthesizing monodisperse CQDs are predominantly based on the work of LaMer and Dinegar, who described how the production of monodisperse colloids is dependent on a rapid nucleation followed by the controlled growth of the existing nuclei (Figure 1). 8,9 Using this approach, Alivisatos and Bawendi et al. … TīmeklisThe first mechanism was the LaMer mechanism9,10 which has the conceptual separation of the nucleation and growth into two stages. LaMer studied the synthesis of sulfur sols from the decomposition of sodium thiosulfate, consisted in two steps: the first to form free sulfur from the thiosulfate and the second form sulfur sols in solution.
