Square-shaped Nd2Sn2O7 Nanocrystals Prepared by Salt-assistant Combustion Method

摘要：

　　Ultrafine square-shaped pyrochlore-type Nd2Sn2O7 nanocrystals were synthesized by a convenient salt-assisted combustion process using glycine as fuel.The products were characterized by X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FT-IR),Raman spectroscopy,Transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM).The results indicate that the products are phase-pure nanocrystals with pyrochlore-type structure.TEM and HRTEM images reveal that the products are composed of well-dispersed square-shaped Nd2Sn2O7 nanocrystals with the average size of 30 nm and the crystallite is structurally uniform and crystalline.The presented method provides a convenient and low-cost route for the synthesis of oxide materials nanostructures.
