Fig. 8. (a, c, and e) Normalized emission spectra at different concentrations within the 1.0 × 10–4–3.3 × 10–8 M range and (b, d, and f) CD spectra at different concentrations within the 1.0 × 10–4–5.2 × 10–6 M range of (a and b) GdC, (c and d) a 1 : 10 GdC + C mixture or (e and f) a 1 : 1 GdC + aC mixture. (g) Speciation profiles (lines; simulated using the values shown in Table 1) and calculated EFRET values at different concentrations (blue open squares) within the 10–2–10–9 M range.
