Studies of Multiple Metal Doped Silicon Clusters and Design of Novel Materials Based on Clusters Containing Silicon and Germanium. KU Leuven
Geometric, Electronic and Magnetic Properties of Transition Metal Doped Silicon Clusters, and Development of a Magnetic Deflection Setup KU Leuven
The aim of the work presented in this thesis is to provide deeper understanding on the geometric, electronic, and magnetic properties of gas phase clusters as a function of size and composition using a combination of the spectroscopic techniques and density functional theory (DFT) calculations. The thesis is divided into four parts. A review of recent research on the structural identification of doped silicon clusters is given in Part I. In ...
Luminescent Lanthanide Doped Nanoparticles as Bimodal Contrast Agents for MRI and Optical Imaging. KU Leuven
This manuscript covers the development of five different multimodal contrast agents for MRI and optical imaging, which are all unique in their design and properties.
The first approach involves linking multiple paramagnetic gadolinium(III)-chelates based on 2-[4,7,10-tris(carboxymethyl)-1,4,7,10-tetrazacyclododec-1-yl]acetate (DOTA) ligand to the surface of NaGdF4:Yb3+,Tm3+ upconverting nanoparticles with an average particle size of 20 ...
Quantum Rules for Nanoclusters. KU Leuven
Nanochemistry recently emerged as a new branch of chemistry, simultaneously expanding into many new areas, and playing a significant role in fields that were domains of engineering or life sciences. Nanochemistry brings together multiple disciplines using chemical theories and experiments to investigate materials at the nano scale. Emerging nanomaterials include the nanoclusters. The elemental clusters are of great interest due to their ...
Polycrystalline Silicon Passivating Contacts for High-Efficiency Silicon Solar Cells KU Leuven
Advancing photovoltaics (PV) for terawatt-scale harvesting of solar energy requires reductions in PV system costs by continuous improvements in silicon (Si) solar cell power conversion efficiencies (η). As the maximum η achievable with the standard p-type passivated emitter and rear cell (p-PERC) technology is limited to ~24% in production, the new n-type tunnel oxide passivated contact (n-TOPCon) technology is increasingly ...
Narrowband phosphors for imaging Ghent University
Conclusions
This dissertation features an investigation of inorganic luminescent materials, activated by transition metal or lanthanide impurities. These materials, which are in this context referred to as phosphors, form a key building block of white LEDs, a technology that has already revolutionized, and will continue to revolutionize, electric lighting in terms of functionality, design and consumption. LED technology is not limited to ...
