摘要：
The capabilities of a plasma-assisted technique based on electrical discharge in liquids for synthesis of N-doped and In-N codoped ZnO nanocrystals have been analyzed. The synthesis was carried out in a reactor containing aqueous ammonium nitrate solution of 0.001M concentration. The pulsed-spark discharges between Zn-Zn and Zn-In electrodes have been used with further deposition of the synthesized particles on the silicon substrates. The optical properties, morphology, and composition of the nanoparticles formed were investigated by means of UV-Vis absorption spectroscopy, SEM, EDX, and XRD. As it followed from the XRD patterns the synthesized product was composed of hexagonal ZnO nanocrystals. The positions of the reflection peaks were observed to be varied with the composition of dopants. The influence of doping level on the structural and optical properties of synthesized nanoparticles has been discussed. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
