Sheet-like ZnFe_2O_4 was prepared by means of a modified citrate precursor method with Fe(NO_3)_3·9H_2O and Zn(NO_3)_2·6H_2O as starting materials. Polyaniline(PANI)/ZnFe_2O_4 nanocomposite was obtained by the in-situ polymerization of aniline in the presence of ZnFe_2O_4. The as-prepared samples were characterized by means of X-ray diffraction, scanning electron microscopy, transmission electron microscopy, infrared and fluorescence spectroscopies. The results show that PANI was deposited on the surface of sheet-like ZnFe_2O_4. X-ray diffraction and infrared spectra further confirmed the formation of PANI/ZnFe_2O_4 nanocomposite. Introducing ZnFe_2O_4 into polymer matrix enhanced the fluorescent emission intensity and thermal stability.
