Generating white light with LED technology requires a trick; one of them is to use color-converting (phosphor) layer that covers the LED chip. Suitable phosphors that can be excited with LEDs are scarce, necessitating research in this area. Complexes of the trivalent lanthanoids are interesting candidates, as their absorption properties can be tuned by modification of the organic part of the molecule, while the emission is line-like in nature and characteristic for the Ln(III) ion. In this thesis, several classes of Ln(III) coordination compounds are explored and their photophysical properties investigated. Several compounds with promising properties, such as a long-wavelength excitation maximum and a high photoluminescence quantum yield are reported.Metals in Catalysis, Biomimetics & Inorganic Material
