Results for 5 nm thick silver films before (top row) and after (bottom row) annealing at 200 °C for 1 h in a vacuum oven: (A) polar plots for scattering of 473 nm laser light, (B) polar plots for fluorescence emission from FITC-HSA coated onto thick silver films, and (C) fluorescence emission spectrum measured at 225° and the real-color photographs of emission from FITC-HSA coated onto silver films. No pol-no polarization, p pol: p polarization, s pol: s polarization.
