Time-resolved fluorescence decay traces of chlorophylls and Chl-mix:PVP films excited by using a picosecond pulse laser and recorded at the emission wavelength λ_emi = 675 nm.

Normalized fluorescence decay traces of the Chl-mix suspended in ethanol (decay rate Γ^(int) = 0.160 ns⁻¹), the Chl-mix:PVP film on blank fused quartz substrate (Γ⁽⁰⁾ = 0.323 ns⁻¹) and the Chl-mix:PVP on a near-percolating silver film with t_d/t_c = 0.94 (Γ = 0.980 ns⁻¹).
