Fig. 3: Time-resolved emission spectra and transition orbital.
From: Charge transfer emission between π- and 4f-orbitals in a trivalent europium complex
Time-resolved emission spectra (λex = 368 nm) of solid-state a Eu-MCPO and b Gd-MCPO at 100 K (a, black line: 0–0.5 ns, red line: 0.5–1.0 ns, blue line: 2.0–3.0 ns, b black line: 0–0.5 ns, red line: 0.5–1.0 ns, blue line: 5.0–44 ns). Normalized by intensity maxima. c Results of the transition orbital analysis from the CT excited to ground state at the structure with large oscillator strength appeared during the structural relaxation using quantum chemical calculations (Fig. S21). Gray spheres represent carbon; red spheres, oxygen; blue spheres, nitrogen; orange spheres, phosphorus; and green spheres, europium.
