　　Abstraet:Nanostuctured Tb3+-doped Gd2O3 particles were synthesized from chloride precursors GdCl3 and TbCl3 by NaOH addition in a polyol medium.Gd2O3∶ Tb3+ particles were encapsulated in a polysioxane shell by being immersed in a mixed solution of APTES and TEOS.The core-shell nanoparticles can be used in the detection of biological molecules.Effect of NaOH quantity on size and luminescent property of nanoparticles were studied.The result showed that the size of nanoparticles increased when NaOH quantity increased 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.
