Figure 3. Common methods for the synthesis of MNCs: (a→b) formation of M(I)-SR complexes, metal atom (M(I)), thiolate ligand (SR), (b→c) reduction growth, (c→d) seeded growth, (c→f) alloying reaction, (c→g) ligand-exchange process, (c→h) self-assembly of metal NCs, and (d→e) evolution from metal NCs to metal nanocrystals[41].
