摘要	A modified polyacrylamide gel route was used to fabricate TbMnO3 nanoparticles. In this route, the aqueous solution of inorganic Tb and Mn salts was gelled by using acrylamide and during the gelation process, acrylamide was polymerized to form a polymer network, which provided a structural framework for the growth of particles. Thermogravimetric (TG) analysis, differential scanning calorimetry (DSC) analysis, Fourier transform infrared spectrometer(FTIR) and X-ray diffraction (XRD) were combinatively used to investigate the thermal decomposition process of xerogel and the formation of TbMnO3 phase. It is demonstrated that high-phase-purity TbMnO3 nanoparticles can be prepared separately by using citric acid and ethylenediamine-tetraacetic acid (EDTA) at a sintering temperature of 800 oC. However, the particle size and morphology of the products are found to be dependent on the choice of chelating agent. Scanning electron microscope (SEM) observation reveals that the particles prepared by using citric acid as the chelating agent are regularly spherical in shape and highly uniform in size with a diameter of about 67 nm, while the sample prepared by using EDTA mainly consists of sphere-, ellipsoid-, and rod-like particles with an average particle size of about 115 nm. In addition, it is found that adding an appropriate amount of bisacrylamide to the precursor solution can lead to a moderate reduction in particle size and a more regular particle morphology. Magnetic hysteresis loop measurements indicate that the TbMnO3 nanoparticles exhibit paramagnetism at room temperature.
