AFM topography images of 1 μm2 areas of set I Au films deposited on (a) sapphire, (b) quartz, and (c) silica.
SEM images of nanoparticles generated during UV laser ablation of 20 nm thick Au films on quartz with an average grain diameter of (a) 33 nm and (b) 62 nm.
Volume relationship between the grain of the 20 nm Au film and the Au nanoparticles generated during laser ablation at (a) UV and green wavelengths (blue diamond and green square, respectively) and (b) IR wavelength (redtriangles). Note logarithmic scale on vertical axis in (b). Error bars represent the standard error associated with the data point.
