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