Abstract:
Zinc oxide is a highly applicable semiconductor material. Wide application of this nanomaterial is connected with wide spectrum of energy band gap, high bond energy, great thermal conductivity, but also with its non-toxicity, antibacterial activity, biocompatibility and biodegradability characteristics. The aim of this paper is synthesis and characterization of silver doped ZnO nanoparticles (ZnO-Ag NP) by using sol-gel method. Obtained samples of silver doped ZnO nanoparticles were characterized by following techniques: Fourier-transform infrared spectroscopy (FTIR), UV/VIS spectrophotometry, X ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX).Efficiency of mentioned synthesis method was examined by FTIR spectroscopy. XRD determined the purity and crystallinity, and wurtzite structure of synthesized material. Surface morphology and the effect of doping were examined using SEM and EDX characterization methods.Results showed better conductivity after doping ZnO nanoparticles with silver and the morphology of synthesized ZnO-Ag NP was in the form of nanorods.
