METHOD FOR PREPARING LIGHT EMITTING NANOPARTICLES USING A CORE/SHELL STRUCTURE, CAPABLE OF SECURING THE EFFICIENT LIGHT EMITTING PROPERTY OF THE NANOPARTICLES

摘要

PURPOSE: A method for preparing light emitting nanoparticles using a core/shell structure is provided to reduce host-guest material consumption by surrounding the external side of a silica nanoparticle with the host-guest material.;CONSTITUTION: A silica nanoparticle is prepared based on a sol-gel reaction. A host-guest shell material with a light emitting property is coated around the core of the silica nanoparticle to obtain a sphere light emitting particle. The host-guest material is composed of a metal ion or a metal oxide. The guest material is one or more selected from erbium, europium, ytterbium, holmium, thulium, or the oxide of the same. The host material is one or more selected from yttrium, gadolinium, vanadium, zinc, titanium, or the oxide of the same.;COPYRIGHT KIPO 2011
