Tīmeklis2024. gada 17. aug. · Since the PL spectrum of particles synthesized for 1 h were in the QD emission range, the synthesis time of 1 h was considered as the proper synthesis time for the next experiments. Moreover, the same reason for controlling the nucleation and growth is shown in Fig. 3b in the Lamer diagram. Consequently, there is a … Das LaMer-Modell, das von dem amerikanischen Chemiker Victor LaMer (1895–1966) entwickelt wurde, erklärt das Wachstum von Nanopartikeln mithilfe eines kinetischen Ansatzes. Ursprünglich beschrieb LaMer damit erstmals die Herstellung von monodispersen Schwefel-Solen. Das Modell wird heute für das Wachstum verschiedenster Nanoteilchen angewandt.
