This study examined the luminescence properties of europium (+3) and terbium (+3) compounds within room temperature ionic liquids. The ionic liquids used in this study were derived from imidazolium cations and varying anions (e.g. Br-, bis(trifluorosulfonyl)amide, …) in order to select for the solvent properties. A number of lanthanide compounds were chosen in order to maximize solubility within the ionic liquids. Spectroscopic properties of lanthanide compounds in ionic liquids were characterized using luminescence, excitation, and time-resolved luminescence measurements. Results from these measurements were used to examine the solvation and coordination environment of the lanthanide ion within each ionic liquid.
