Optical Characterization of SERS Substrates Based on Porous Au Films Prepared by Pulsed Laser Deposition

Figure 4

The transmittance spectra of the por-Au films prepared at the one pulse energy 5 J/сm² and the number of the laser pulses measured at various argon pressures: 1, 1′: 13.5 Pa and 2, 2′: 100 Pа, and distances : 1, 2: 5 mm and 1′, 2′: 15 mm.
