Preparation and study of rare earth oxide nanoparticles with core-shell structure

摘要：

　　Core-shell nanoparticles Gd2O3:Tb3+/SiOx were obtained by encapsulating Gd2O3:Tb3+ in a polysiloxane shell.We studied the influence of two kinds of reagents (NaOH and Bu4NOH) reacting with precursor solution on size and luminescent property of nanoparticles.The result showed that the reaction involving NaOH was more favorable to the growth of nanoparticles, thus enhanced the energy transfer between the core and the shell of particles and improved their luminescent intensities.

关键词： Core-shell structure Gd2O3:Tb3+/SiOx NaOH Bu4NOH
