Figure 3
(a,b) UV-vis extinction spectra and (c,d) size distribution of the irradiated Ge colloid after increasing number of jet passages in water (a,c) and isopropanol (b,d), respectively. Black-0 passage; Red-10 passages; Green-50 passages; Blue-100 passages. PPI values as a function of specific energy from 0 to 100 in 10 passages increments for both liquids are shown as the inset figures in Fig. 2(a,b). One passage equals 0.42 J/g and 0.86 J/g laser energy input of water and isopropanol, respectively. (e,f) Histograms showing Feret diameter of particles before and after laser melting. The relationship between relative mass frequency and hydrodynamic particle diameter as shown in Fig. 3c,d was extracted from analytical disc centrifuge measurements.
