英文摘要	Sm₂Zr₂O₇ nanocrystallines were synthesized via hydrothermal method using polyethyleneglycol (PEG), cetyltrimethyl ammonium bromide (CTAB) and sodium dodecylbenzene sulfonate (SDBS) as surfactants, respectively. The effects of surfactants on the structural evolution and the crystal growth of Sm₂Zr₂O₇ were investigated by X-ray diffraction (XRD), thermogravimetric analysis and differential scanning calorimeter (TG/DSC), Raman spectroscopy, field emission scanning electron microscope (FESEM) and high resolution transmission electron microscopy (HRTEM), separately. The as-prepared products have a spherical morphology, and the average particle sizes are in the range of 4–9 nm. The structure transition from fluorite to pyrochlore structure occurred at 1300 °C with PEG and SDBS, which can be restrained by adding CTAB. The activation energy of crystal growth is significantly dependent on the surfactants, which is in the order of SDBS > PEG > CTAB. Moreover, the effects of surfactant on the sintering-resistance property of the products are also discussed.
