Figure 4: Size-dependent photokinetics.

(a) Inverse first half-lives as a function of the droplet radius for a laser power of 1 mW. Black circles: statistically evaluated experimental data. Error bars show 1 s.d. Full blue line: model prediction including nanofocusing and scattering effects. The calculations are for a quantum yield of 7 × 10⁻⁶. Dashed red line: model prediction for a hypothetical bulk limit, that is, excluding contributions from nanofocusing and scattering. Distribution of the light intensity inside droplets at t=0 s for (b) a 0.5 μm droplet and (c) a 20 nm droplet. The colour scheme is relative to an incident light intensity of 1.
