Recently, spinel ferrite materials (MFe2O4; M= Fe, Ni, Co, Mg etc.) have been so attractive, such as inductors, magnetic sensors, magneto-optical storage and memory devices etc. in quite different areas. In the spinel ferrite material group, ZnFe2O4 (zinc-ferrite) has high resistance, mechanical stability and low dielectric losses, especially in high frequency applications. The need for ZnFe2O4 materials with simple synthesis process and low production/power cost increases research and development in this direction.In this study, zinc-ferrite films were synthesized by chemical bath deposition on ITO substrates, using different concentration of complex agent. Ammonia was preferred as a complex agent. Structural, surface morphology and optical properties of the films were investigated with XRD, SEM and UV Vis/Raman spectroscopy devices, respectively which depend on the ammonia ratio and therefore pH of solution. In light of the data obtained from XRD spectra, it was determined that crystallization increased with the increase in ammonia ratio. Ammonia ratio changes have been observed to cause nanoparticles in different forms in SEM-surface morphology images. In addition, optical properties of the films have improved with the increase of ammonia ratio.
