Spatially- and temporally-resolved distributions for [1O2]rx (a and d), [3O2] (b and e) and [S0] (c and f) for 15 and 150 mW/cm, respectively. r is the radial distance relative to the center of the linear source (LS). For a given total energy released per unit length, 15 mW/cm treatment deposits higher [1O2]rx compared to 150 mW/cm (a vs. d). Oxygen recovery, due to 1O2-mediated photobleaching effect, is clearly shown in (b) (15 mW/cm), which is consistent with the significant photosensitizer degradation shown in (c).
