Abstract :
Temporal evolution of the density, nHS, of photoexcited high-spin (HS) sites in a spin-crossover film (Nafion-[Fe(Htrz)3]; Htrz=1,2,4-4H-triazole) was investigated at 4 K under various excitation power densities, I. We have found that the temporal evolution of nHS slows down when I approaches a critical excitation power density (Ic≈250 mW/cm2).
