Fluorescence properties of a uranyl(V) tricarbonate complex were determined at T = 153 K by time-resolved laser-induced fluorescence spectroscopy (TRLFS) for the first time. The fluorescence emission bands of the uranyl(V) tricarbonate complex were detected between 380 and 440 nm with the maxima at 404.7 nm (excitation with 255 nm) and 413.3 nm (excitation with 408 nm). Besides, the fluorescence lifetime was determined to be 120 micro-sec at 153 K.
