Study of Doped Zinc Oxide Nanowires by X-Ray Photoelectron Spectroscopy

Zinc oxide nanowires were synthesized by hydrothermal method using cetyltrimethylammonium bromide (CTAB) as a surfactant. Samples of nanwires doped with iodine and bromine were also prepared. The influence of CTAB and doping on the microstructure and surface functional composition of samples was analyzed by X-ray photoelectron spectroscopy and scanning electron microscopy. It was found that doping with iodine and bromine leads to an increase in the concentration of OH groups on the surface of zinc oxide nanowires. ZnO nanocrystals grow separately from a single center when CTAB is added to growth solution.
