Fig. 3: Chiroptical properties of plasmon-micelle composites.
a CPL spectra of R−1M (yellow line) and S−1M (yellow dash line) in water excited by 400 nm. UC-CPL spectra of R−1UCM (blue line), S−1UCM (blue dash line), R−1UCM/AuNR653 (red line), and S−1UCM/AuNR653 (red dash line) in deaerated water excited by 635 nm laser. b Dissymmetry factor glum values of CPL, UC-CPL, and plasmon-enhanced UC-CPL at peak values of emission. All error bars show mean ± standard deviation. n = 3 independent experiments. c CD dissymmetry factor gCD of R-1M (blue line), S-1M (blue dash line), R-1M/AuNR653 (red line), and S-1M/AuNR653 (red dash line) versus wavelength. d Two-dimensional transient absorption spectra of R-1UCM/AuNR653 in deoxygenated water. e Transient absorption spectra of R-1UCM and R-1UCM/AuNR653 in deoxygenated water after excitation at 635 nm, delay time: 1 ps. f Upconversion decay at 476 nm of R-1UCM and R-1UCM/AuNR653. [R-1] = 5 × 10−5 mol L−1, [PdTPBP] = 10-5 mol L−1, [CTAB] = 10−2 mol L−1, molar ratio AuNR653/R−1 = 3 × 10−6/1. A 635 nm short-pass filter was used. The power density of the 635 nm laser was 2000 mW cm−2. Source data are provided as a Source Data file.
