From: Circularly polarised luminescence laser scanning confocal microscopy to study live cell chiral molecular interactions

Fig. 3

A One photon excitation (λem = 615 nm) (solid purple line) and two-photon excitation (maroon dots) spectra (λem = 615 nm) of Eu:L1. B Excitation power dependency (green diamonds) of the 2PE induced photoluminescence (PL) intensity, slope 1.80 ± 0.1, σ2 = 73 ± 3 GM (10−50 cm4s/photon). C One (λex = 340 nm, solid red line) and two-photon induced (λex = 700 nm, solid blue line) emission spectrum of the depicted (insert) Λ- and Δ Eu:L1. D One photon (main figure) and (insert) two-photon CPL spectra of Λ- and Δ Eu:L1 (solid black and red line, respectively). Spectra recorded in NMP.
