Samples of nanostructured zinc oxide with wurtzite structure and different morphologies of aggregates have been synthesized using oxalate ZnC2O4 center dot 2H(2)O, glycerolate Zn(OCH2OCHCH2OH), formate Zn(HCOO)(2) center dot 2H(2)O, glycolate Zn(OCH2CH2O), formate glycolate Zn(HCOO)(OCH2CH2O)(1/2), acetate Zn(CH3COO)(2) center dot 2H(2)O, succinate Zn(OO(CH2)(2)OO) and hydroxide Zn(OH)(2) as precursors. The optical absorption and the EPR spectra were measured at room temperature, whereas the magnetic properties were assessed in the temperature range from 5 to 330 K. All synthesized samples exhibit ferromagnetic properties both at 5 K and at room temperature.
