Research Abstract

YVO_4:Bi^<3+>,Eu^<3+> nanoparticles emitting red under the excitation of ultraviolet light were hybridized with PMMA mirobeads through electrostatic interaction. In addition, YAG:Ce^<3+> nanoparticles emitting green under the excitation of blue light as well as YAG/YIG core/shell nanoparticles were hybridized with PMMA mirobeads through electrostatic interaction.
