Indium phosphide magic-sized clusters: chemistry and applications

This paper reviews developments in the synthesis of InP quantum dots (QDs) and research on InP magic-sized clusters (MSCs), which occur as intermediates during the growth of InP QDs. We classify research on InP MSCs into (1) synthesis and characterization and (2) applications. Several InP MSCs have been developed using low reaction temperatures or strong binding ligands. InP MSCs passivated by carboxylate, amine or phosphonate ligands and InP MSCs that incorporate heterogeneous atoms (Cl or Zn) have been synthesized. We also review tools to characterize MSCs and show the intermediate characteristics of InP MSCs. InP MSCs have been used as synthesis precursors for spherical InP QDs and nonspherical InP nanostructures, such as elongated, branched, and hyperbranched/dendrimer-like morphologies. We also present MSC-mediated growth mechanisms involving fragments, monomers or other nanoclusters. Research on the chemistry and applications of InP MSCs has uncovered the formation process of InP nanomaterials. Developments in the luminescent properties of InP MSCs, InP QDs and elongated InP nanostructures would be useful in displays. This review encompasses syntheses, characterizations, and applications of InP magic-sized clusters (MSCs) which are originally found as intermediates during the growth of InP quantum dots (QDs). Various tools to characterize MSCs and the intermediate characteristics of InP MSCs and InP MSCs having incorporated heterogeneous atoms such as chlorine or zinc are discussed. Developments in the syntheses of InP QDs and MSC-mediated growth mechanisms involving fragments, monomers or other nanoclusters are also addressed.
