Experimental and theoretical investigation of indium phosphide quantum dot growth mechanisms
… to study growth mechanisms of InP QDs from precursor conversion to final nanocrystal formation. As the key experimental platform, a high temperature and high pressure microfluidic system was first applied to study the effect of group V precursor reactivity on the QD growth. High-pressure …

GROWTH OF SILICA-BASED NANOPARTICLES: CONTROLLING STRUCTURE AND FUNCTION
Silica chemistry provides a uniquely tunable platform for nanoparticle synthesis, where particle size, nanoscale morphology, and surface properties can be precisely controlled. Recent advances demonstrate that conveniently accessible parameters, including silica precursor chemistry, solvent, and …

Synthetic Design of Optical Emitters
… of this thesis, I detail a new approach to the precursor chemistry of indium arsenide (InAs) QDs based on the redox chemistry of In. The judicious combination of an As(III) and an In(I) precursor yields an atomeconomical redox couple employing safe and commercially available compounds. A …

Synthesis and characterization of infrared quantum dots
… power and contradicts what is known about the chemistry of QD growth. I try to relate my experimental approach and my conclusions to our understanding of the mechanism of particle growth. This approach led me to explore the role of precursor conversion rate in the growth of III-V QDs and to …

Engineering of Alkali Metalorganic Precursors: Synthesis to Mechanistic Aspects
… titanate (PZT). However, the lack of available precursor chemistry for these alkali metals has pushed the scientific community to explore novel routes to synthesize alkali metal precursors. In this regard, metal β-diketonates comprise a unique class of complex where the monovalent bifunctional …

Studies in Advanced Oxy-combustion Technologies
… observed, the radical pool zone and the soot precursor zone which is located on the fuel side of the flame. The onset threshold of soot precursors (C6H5 and C6H6) on the high temperature side of the soot precursor zone is characterized by the depletion of radicals. The role of the hydrogen …

Heavy-metal-free colloidal nanocrystal heterostructures – synthetic chemistry and growth mechanisms
… a better understanding of the synthetic chemistry and the growth mechanisms for heavy-metal-free nanocrystal heterostructures is critical before their commercialization potential becomes reality. Here, we have developed novel synthetic strategies to achieve the anisotropic growth of …
