Electrodeposition of Zn was performed in 1-allyl-3-methylimidazolium bromide (AMImBr) containing ZnBr2. The effects of the temperature and salt concentration on the morphology and composition of the electrodeposited Zn were observed and analyzed using field-emission scanning electron microscopy and X-ray diffraction. Silvery, smooth, and compact Zn deposits with a good adherence were obtained from the electrolyte. The particle size increased with the temperature. Raman spectra of the electrolyte indicated that Zn2+ and Br- could form complex ions. ZnBr42- was the dominant species when the ZnBr2 concentration was C-ZnBr2 <= 2.0 mol.kg(-1); the peak from the ZnBr3- complex was observed for C-ZnBr2 >= 2.5 mol.kg(-1). The morphology of the electrodeposited Zn was influenced by the ZnBr2 concentration; the complex ion species changed the shape of the primary particles of the electrodeposited Zn.
