In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Influence of TOPO and TOPO-CdSe/ZnS quantum dots on luminescence photodynamics of InP/InAsP/InPHeterostructure nanowires, published in 2021, which mentions a compound: 78-50-2, mainly applied to trioctylphosphine oxide indium arsenic phosphorus quantum dot optical property; TOPO ligands; luminescence kinetics; molecular-beam epitaxy; nanowires; reverse transfer, Electric Literature of C24H51OP.
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 Auassisted mol. 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.
There is still a lot of research devoted to this compound(SMILES：CCCCCCCCP(CCCCCCCC)(CCCCCCCC)=O)Electric Literature of C24H51OP, and with the development of science, more effects of this compound(78-50-2) can be discovered.
