Abstract

${{\rm Gd}_2}{{\rm O}_3}{:}{{\rm Tb}^{3 +}}$ nanoparticles were synthesized by using diethylene glycol as a solvent and doped with 3 mol% ${{\rm K}^ +}$ ions. ${{\rm Gd}_2}{{\rm O}_3}{:}{{\rm Tb}^{3 +}}$, ${{\rm K}^ +}$ nanoparticles were calcinated at 600°C, 700°C, 800°C, and 900°C and subjected to the analysis of x-ray diffractometer, transmission electron microscope, Fourier transform infrared spectrometer, fluorescence spectroscopy, and magnetization. The experimental results showed that as the calcination temperature increased from 600°C to 800°C, the morphology and particle size of the ${{\rm Gd}_2}{{\rm O}_3}{:}{{\rm Tb}^{3 +}}$, ${{\rm K}^ +}$ nanoparticles did not change significantly; whereas when the calcination temperature rose from 800°C to 900°C, the structure of ${{\rm Gd}_2}{{\rm O}_3}$ particles changed from cubic to monoclinic. As the temperature increased (below 800°C), the crystallinity of the cubic particles increased and the surface defects of the particles decreased, resulting in an increase in fluorescence intensity. For the monoclinic particles, the fluorescence intensity was significantly decreased and the magnetization was increased. The measured magnetic results confirmed the good paramagnetism of the synthesized nanoparticles.
