How Does Precursor Concentration Affect Nanoparticle Synthesis?
During the synthesis of nanoparticles, precursor concentration influences several aspects:
Nucleation Rate: Higher precursor concentrations generally increase the nucleation rate, leading to more nucleation sites and smaller particle sizes. Particle Growth: Lower precursor concentrations tend to favor the growth phase, resulting in larger particles. Shape Control: The concentration of precursors can also affect the shape of nanoparticles, as different concentrations may favor the formation of specific crystal facets. Aggregation: Too high a concentration can lead to aggregation of nanoparticles, which is undesirable for many applications.
