solution (Hermodson 1996). The scattered light will either result in mutually destructive phases or cancel each other out or in mutually constructive phases to produce
a detectable signal (Berne and Pecora 1977). The particle size and distribution are
evaluated from the signal. The schematic diagram of the basic principle of DLS is
shown in Fig. 14.
DLS measurement was employed to compare the particles size distribution of
ZnO and TiO 2 nanoparticles under different sonication times (Fig. 15). Accordingly, particle size decreases with increased sonication time for both ZnO and TiO 2
