Langmuir–Blodgett monolayers of InP quantum dots with short chain ligands

Synthesis, Characterization, and Self‐assembly of Colloidal Quantum Dots

“…Organization of nanocrystals into ordered structures is an important issue related to the integration of QDs into devices that have practical applications [178]. In this regard, self-assembly methods have demonstrated great potential for fabrication of photonic, electronic, or magnetoelectronic devices with ordered QDs structures [179].…”

“…For example, the LB method has been used by several groups to deposit nanomaterials such as Au [183], Ag [184][185][186], Pt [187], Fe 3 0 4 [188], CdS [189], CdSe [190], and InP [191] onto solid substrates. The LB technique has myriad uses, but generally is used for one of two purposes.…”

The study of the formation of monolayers of quantum dots at different temperatures

“…These molecules separate QD or their aggregates from each other. Nowadays, processes of a monolayer formation of different types of QD [9] or differing by the type of stabilizer molecules [10] has been studied. The periodic cycle of compression and decompression was used for obtaining a close packed phase of QD in the monolayer [11].…”

Assembly of CdSeS(ZnS) Quantum Dots in Langmuir Films with Tertiary Alkyl Phosphine Ligands

“…Additionally, ligand-ligand interactions play a dominant role in interparticle dynamics, and using modified or altogether different ligands can drastically change the assembly of SQDs in a Langmuir film. Electron transfer is highly dependent on the ligand structure, with short chain ligands generally providing more transparent tunneling barriers during TEM studies 19 . Trioctyl-phosphine oxide (TOPO) is by far the most popular choice for a ligand, although investigations of other ligands are scarce.…”
