Sažetak
In this work the pulsed laser ablation of Ag coated ZnO target in water is performed in order to synthesize the colloidal solution of Ag doped ZnO nanoparticles. Ag coated ZnO targets with various thickness of Ag layer are previously synthesized by pulsed laser deposition (PLD). The thickness of Ag layer at ZnO substrate was controlled by modifying the number of laser pulses in ablation of Ag target in PLD. The ratio of Ag dopant in ZnO nanoparticles strongly depends on the thickness of Ag layer at ZnO target. These nanoparticles were characterized by number experimental methods as XRD, XPS, SEM, EDS and UV-VIS spectrophotometry in order to determine and analyse their crystal and stoichiometric structure, size distribution, shape, optical properties (photoabsorbance, bandgap) and mass concentration. The photocatalytic performance in degradation of Methylene Blue under UV and visible light is tested for different ratios of Ag dopant in ZnO nanoparticles. The maximal photocatalytic efficiency under UV light is reached at some optimal Ag ratio, with MB photodegradation rate almost twice larger than one obtained while using pure ZnO nanoparticles.
