AbstractThis 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.

The passivation influence by ligands coverage with trioctylphosphine oxide (TOPO) and TOPO including colloidal CdSe/ZnS quantum dots (QDs) on optical properties of the semiconductor heterostructure, namely an array of InP nanowires (NWs) with InAsP nanoinsertion grown by Au-assisted molecular beam epitaxy on Si (111) substrates, was investigated. A significant dependence of the photoluminescence (PL) dynamics of the InAsP insertions on the ligand type was shown, which was associated with the changes in the excitation translation channels in the heterostructure. This change was caused by a different interaction of the ligand shells with the surface of InP NWs, which led to the formation of different interfacial low-energy states at the NW-ligand boundary, such as surface-localized antibonding orbitals and hybridized states that were energetically close to the radiating state and participate in the transfer of excitation. It was shown that the quenching of excited states associated with the capture of excitation to interfacial low-energy traps was compensated by the increasing role of the “reverse transfer” mechanism. As a result, the effectiveness of TOPO-CdSe/ZnS QDs as a novel surface passivation coating was demonstrated.
