1. X-ray structural studies of lanthanide alkoxides
Abstract : A number of homo- and hetero-metallic lanthanide (oxo-)isopropoxides with the general composition LnxMyO(OiPr)p(HOiPr)q has been structurally characterized by means of single crystal X-ray diffraction. The studied compounds may be divided into five groups by the geometry of their metal-oxygen core. READ MORE

2. Unravelling Sensitisation and Quenching Pathways in Lanthanide Luminophores
Abstract : Lanthanide (Ln) ions find use in cellular detection and probing of many analytes, owing to their unique photophysical properties. However, to make the Ln emission efficient, one has to develop a light-harvesting antenna, which is an organic chromophore that absorbs and transfers energy to the Ln. READ MORE

3. Light-Matter Interaction and Quantum Computing in Rare-Earth-Ion-Doped Crystals
Abstract : In this thesis, crystals of yttrium orthosilicate (Y2SiO5) that are randomly doped with another rare-earth element, such as praseodymium (Pr), europium (Eu), or cerium (Ce), are investigated with lasers locked to ultra-stable cavities using the Pound-Drever-Hall locking technique. Many of these rare-earth elements have long-lived 4f-4f transitions, hundreds of microseconds to a few milliseconds, with even longer ground hyperfine lifetimes of up to several days. READ MORE

4. Nuclear spin interactions and coherent control in rare-earth-ion-doped crystals for quantum computing
Abstract : This thesis work concerns studies of two rare-earth-ions, praseodymium (Pr3+) and europium (Eu3+), doped into a yttrium orthosilicate (Y2SiO5) crystal for applications in quantum computing. The nuclear spin levels of these ions can have very long coherence times, up to several hours. READ MORE
