Abstract

(Nd0.93Sm0.07)2O3 nanocrystalline powders were prepared using modified Pechini method. Powder X-ray diffraction was used to study the structural characterization of the synthesized sample and the results confirmed that Sm3+ doped Nd2O3 nanoparticles having a nanocrystalline structure with a hexagonal phase and space group were formed with lattice parameters a=b=3.8348Ã…, c=6.0031Ã…. These parameters were refined using CELREF software and the cell parameters were refined to give minimum R factor. The surface morphology and the size of the particles were examined using SEM and TEM. The surface micrographs showed small amount of agglomeration. TEM results also confirmed that the synthesized particles are in nanosize. The EDX spectroscopy confirmed the purity of the synthesized sample. The optical properties of the sample were studied using U-V data analysis and photoluminescence studies. The results of the optical studies proved that these materials can be highly efficient in solid state lightings.
