The preparation of metal nanoparticles for plasmonics according to the LaMer Diagram is described, and this knowledge is extended to single-crystalline nanoparticles with variations in crystal habit, nanorods, and nanoplates. This is reinforced by knowledge of the preparation of photographic Ag and AgX nanoparticles. Formation mechanisms of reduction sensitization and latent image centres (Ag2 and Agn with n≥4) serve as nuclei for Ag nanoparticles. Photographic development provides knowledge of the growth of small Agn clusters in the presence of silver ions and reducing agents. Descriptions of the growth of AgX nanoparticles include protective colloids and apparatus for this. Mechanisms for preparing all the possible single-crystalline nanoparticles with fcc structure, tabular nanoparticles, core/shell, and epitaxial nanoparticles with different AgXs, together with methods of preparing nanoparticles with monodispersity and enhanced anisotropy in shape and arranging them, are also discussed.

Keywords:   LaMer diagram, nucleation-growth model, metal nanorod preparation, metal nanoplate preparation, protective colloid, nanoparticle preparation apparatus, latent image formation, crystal-habit modification, monodispersed nanoparticle preparation, nanoparticle arrangement
