Synthesis and Characterization of Neodymium Zirconate Nanocrystals Doped with Aluminium Ions by a Salt-Assistant Combustion Method

Abstract:

Neodymium zirconate nanocrystals doped aluminium ion Nd_xAl_2-xZr₂O₇ with pyrochlore structure were prepared by a salt-assistant glycine combustion method. Zirconium nitrate, aluminium nitrate and neodymium nitrate were used as chemicals, and glycine was used as burning agent. The as-prepared Nd_xAl_2-xZr₂O₇ nano-crystals were characterized by XRD, FT-IR, TEM and HRTEM. The results showed the Nd ions can be partially replaced by Al ions. For crystalline Nd_1.9Al_0.1Zr₂O₇, there are four strong diffraction peaks at 2θ = 29.02°, 33.70°, 48.37° and 57.37° corresponding crystal faces are 0.308nm, 0.266nm, 0.188nm and 0.161 nm, respectively, which indicates that the interstices of corresponding crystal faces are smaller than that of Nd₂Zr₂O₇. Furthermore, the fluorescent properties of Nd_1.9Al_0.1Zr₂O₇ nano-crystals evaluated by the fluorescence spectra indicate that the prepared nano-crystals are a kind of potential fluorescent-emitted material.
