Wavelength-dependent nonlinear absorption of gold nanocages

Fig. 4. Open-aperture Z-scan curves for (a) gold nanocages at 550 nm and 300 μJ, (b) gold nanocages at 550 nm and 800 μJ, (c) gold nanocages at 600 nm and 300 μJ, (d) gold nanocages at 600 nm and 800 μJ, (e) gold nanocages at 650 nm and 300 μJ, and (f) gold nanocages at 650 nm and 800 μJ. The dots are experimental data, while the solid lines are the generated theoretical fit.
