Reflectivity curves measured for a thin gold film on an SiO2/Si substrate. The exposure time was 1000 s for curve a, 100 s for curve b, 10 s for curve c and 1 s for curve d. b–d are each shifted two orders of magnitude along the vertical axis for clarity. Curve o was measured with the angle-scan method. Other curves shown by small black filled circles are the same as curve o, shifted for comparison with curves b–d. |
