1. Photoinduced Electron Transfer in Luminescent Lanthanide Complexes
Abstract : Luminescence from the trivalent lanthanides is used for detection in biological systems. Lanthanide luminescence is usually sensitized by a light-harvesting organic chromophore (’antenna’). An ideal emitter has an antenna that efficiently transfers energy to the lanthanide, and a ligand that shields the metal from quenching solvent molecules. 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. Development and Multicolor Imaging Applications of Lanthanide-Based Luminescent Probes
Abstract : The study of biological analytes in their native environment is a major challenge for biochemistry and molecular biology. Luminesce spectroscopy is well suited for this task due to its non-invasiveness, high spatial and temporal resolution, and high signal to noise ratio. READ MORE

4. Energy Transfer Processes and Quenching Pathways in Lanthanide Complexes: The Role of Structural Changes
Abstract : Due to their unique magnetic and luminescent properties, trivalent lanthanides (Ln(III)) have been widely utilised in cellular imaging. Ln(III) luminescence is usually sensitized by a light-harvesting ‘antenna’, a chromophore that can transfer the excitation energy to the Ln(III). READ MORE

5. Lanthanide Metal-Organic Frameworks and Hierarchical Porous Zeolitic Imidazolate Frameworks : Synthesis, Properties, and Applications
Abstract : This thesis presents the synthesis, properties, and applications of two important classes of metal-organic frameworks (MOFs); lanthanide MOFs and hierarchical porous zeolitic imidazolate frameworks (ZIFs). The materials have been characterized using a wide range of techniques including diffraction, imaging, various spectroscopic techniques, gas sorption, dynamical light scattering (DLS) and thermogravimetric analysis (TGA).
