Fig. 2: Steady-state and microsecond time-resolved CPL spectroscopy of the chiral standard Eu[(+)-facam]3 in DMSO solution.
From: Broadband transient full-Stokes luminescence spectroscopy
Structure of the chiral standard Eu[(+)-facam]3 is shown at the top right. a, Total steady-state luminescence intensity (405 nm continuous wave excitation, 450 nm long-pass filter). The inset shows weak emission on the blue side, partially cut off by the filter. b, Steady-state CPL spectrum showing the intensity difference ∆I between LCP and RCP luminescence, normalized to the maximum total luminescence intensity. The main CPL features are labelled, 5D0 → 7F1 near 595 nm and 5D0 → 7F2 near 615 nm. c, Steady-state spectrum of the luminescence dissymmetry factor glum. d, Time-resolved total luminescence spectra (343 nm excitation pulsed at 500 Hz, 50 µs time bins) at selected gate delays. e, Time-resolved CPL spectra at selected gate delays. f, Time-resolved spectra of the luminescence dissymmetry factor at selected gate delays. g, Intensity and dissymmetry factors as a function of time at the 5D0 → 7F2 peak. h, Intensity and dissymmetry factors as a function of time at the 5D0 → 7F1 peak (small upticks at 450 μs in g and 650 μs in h are probably because of cosmic rays).
