- aggregation title "Synthesis and self-assembly of colloidal quantum dots".
- aggregation abstract "In this work, we study the synthesis and self-assembly of colloidal quantum dots (QDs). First, the InP and CdSe QDs are synthesized using the hot-injection synthesis procedure, and the optical and crystallographic properties are characterized via UV-vis absorbance and photoluminescence spectroscopy and X-ray diffraction. The photoluminescence properties of the CdSe dots are optimized by surrounding the particles with a CdS or ZnS shell. The particles are further characterized via Transmission Electron Microscopy (TEM). Nuclear Magnetic Resonance is used to access information about the ligand molecules which stabilize the particles. Next, the possibilities of Langmuir-Blodgett (LB) and Langmuir-Schaefer (LS) deposition are explored to produce QD monolayers and multilayers. The layer quality is assessed via Atomic Force Microscopy, Scanning Electron Microscopy and TEM. We see that the LS and LB techniques both yield excellent mono- and multilayers, although LS deposition yields different results on hydrophilic and hydrophobic substrates. Combination of LB or LS deposition with optical lithography yields micropatterned layers. Also phase transitions of Langmuir layers upon compression beyond the collapse pressure are studied, and a thermodynamic model for the transitions is suggested. Finally, the effects of Atomic Layer Deposition of aluminium oxide layers on the photoluminescence properties of the QD layers is studied.".
