Influence of NaOH quantity upon the size and luminescent property of core-shell Gd2O3:Tb3+/SiOx nanoparticles

Abstract : Nanostuctured Tb3+-doped Gd2O3 particles were synthesized from chloride precursors GdCl3 and TbCl3 by NaOH addition in a polyol medium. Then, Gd2O3: Tb3+ particles were encapsulated in a polysioxane shell by being immersed in a mixed solution of APTES and TEOS. Effect of NaOH quantity on size and luminescent property of obtained core-shell nanoparticles was studied. The result shows that the size of nanoparticles increased with the increase of NaOH quantity from 30% to100% of stoichiometry. The emission intensity of core-shell nanoparticles increased with the size of particles due to the enhancement of energy transfer between core and shell.
