Square-Shaped Nd2Sn2O7 Nanocrystals Prepared by Salt-Assistant Combustion Method

Article Preview

Abstract:

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.
