Preparation and their Fluorescent Property of Sm2Zr2O7 and Sm2(Zr0.7Ce0.3)2O7 Powders

Article Preview

Abstract:

Pure Sm2Zr2O7 and Sm2(Zr0.7Ce0.3)2O7 nano powders were prepared by sol-gel method using zirconium nitrate and samarium nitrate as raw materials, citric acid as solvent and dispersant. The synthesized powders were characterized by XRD, Ft-IR, BET, SEM and Emission spectra. The effect of thermal temperature on particle size of the nano-powders were studied and single phases of Sm2Zr2O7 and Sm2(Zr0.7Ce0.3)2O7 were completely formed at 900°C. The obtained powders consist of abnormal particles with agglomerated structures in size range 7-10nm. Moreover, the strong fluorescent properties of the synthesized products show that these two kinds of powders are potential fluorescent emitted materials.
