X-Ray Excited Optical Luminescence from Ru(bipy)_3~(2+) and Ru(phen)_3~(2+) in the Energy and Time Domains

摘要

Recent observations of XEOL (X-ray Excited Optical Luminescence) from prototype Ru(II) complexes with excitation energies at various absorption edges of Ru, C and N, and corresponding optical XAFS (photoluminescence yield) are reported. Time-resolved XEOL using the synchrotron light pulse from the Advanced Photon Source in top-up mode and the Canadian Light Source operating in single bunch mode are also noted. These results are discussed in terms of the electronic structures of the complexes, spin-orbit coupling and radiative decay dynamics of the systems.
