EPR spectroscopy has been used to investigate ferromagnetism and oxygen vacancies in nanocrystalline ZnO thin films derived from different zinc acetate sol concentrations on quartz substrate by sol-gel process. In low sol concentration ZnO thin film, a broad ferromagnetic EPR resonance signal of g- value about 2.000 is observed due to zinc vacancies. While on increasing sol-concentration, a narrow EPR resonance signal superimposed on broad line and only narrow line signal of g- value 1.9264 appears due to the fo rmation of oxygen vacancies in films during synthesis.
