Beschreibung
The aim of this thesis is related to synthesis and investigation of different rare-earth doped nanomaterials that are prepared via microwave-assisted synthesis in ionic liquids (ILs). The main research has been focused on shifting the excitation wavelength from the UV-region to the visible light in order to establish efficient LED phosphors. The combination of microwave heating and ionic liquids as reaction media showed superior benefits for the rapid synthesis of different nanomaterials over the conventional heating methods, especially in terms of reaction time, high crystallinity, low defects, and thus high quantum yields.
