Figure 9
Static XRR measurements with the reflected intensity normalized by the Fresnel intensity (R/Rf) and the associated fits are shown for water and 0.5 M NaI solution with (red) and without (black) laser excitation. A 258 nm laser beam with a diameter of 15.3 mm and a fluence of 5.4 µJ cm−2 was used to continuously illuminate the sample. |
