In this dissertation, microwave chemistry is employed to synthesize a variety of different crystalline nanoparticles (NPs). This introduction will describe the structures, properties
and applications of the NPs studied within the dissertation, with a main focus being on ligand sensitization for the goal of enhanced luminescence. The use of metal acetylacetonate
complexes to make Europium (III) doped Ytrrium (Y₂O₃) NPs is explored, where the acetylacetonate acts both as a source of oxygen for the synthesis of Y₂O₃, as well as an organic
chromophore acting as an "antenna" for the absorption of light and subsequent excitation transfer to the incorporated Europium (III) (Chapter 2). Other host materials are investigated by
method of metal acetylacetonate decomposition to synthesize a variety of different nanospinels, having the general formula AB₂X₄, with sulfide variants made by decomposition of
diethyldithiocarbamate, (Chapter 3). The antenna ligand thenoyltrifluoroacetone (tta), which is known to undergo a Dexter energy transfer (DET) mechanism to efficiently sensitize Europium
(III) emission, is used to determine the distance of energy transfer in Europium (III) doped nanospinels by passivating the surface of the nanospinel with a tta (Chapter 4). A variety of
ligands are explored in order to optimize the sensitization efficiency in relation to the difference in energy between the singlet and triplet levels of the ligands versus the ⁵D₀ and ⁵D₄
energy levels of Europium (III) and Terbium (III) respectively (Chapter 5). / A Dissertation submitted to the Department of Chemistry and Biochemistry in partial fulfillment of the Doctor of Philosophy. / Fall Semester 2015. / October 28, 2015. / Includes bibliographical references. / Geoffrey F.
