Lifetime quenching as a function of O2 concentration of a H2O solution containing 0.9 × 10−7 mol 1 adsorbed onto PVG (in black, left). Amplitude quenching as a function of O2 concentration of a H2O solution containing 0.9 × 10−7 mol 1 adsorbed onto PVG (in blue, right). Samples were excited with a 10 ns 417 nm light pulse (0.6 mJ/pulse), and the transient absorption was monitored at 470 nm.
