Luminescence study of the optically active uranyl crystals: NaUO2(CH3COO)3

Abstract Luminescence spectra of NaUO 2 (CH 3 COO) 3 single crystals at 4.2 K have been investigated by means of site selective excitation technique, circularly polarized luminescence and time-resolved luminescence spectroscopy. It has been found that the splittings in the pure electronic and their vibronic transition lines are ascribed to the transitions from two different emitting sites.
