- - Light conversion emitting device comprising anisotropic metal nanoparticles-dielectric core-shell nanostructure

摘要

The present invention uses anisotropic nanoparticles having a metal-dielectric core-shell structure to induce emission intensity amplification of various light emitting materials capable of being introduced into a light emitting device, Emitting device.When anisotropic metal nanoparticle-dielectric core-shell nanoparticles having an aspect ratio in the light emitting layer of the light emitting device as in the present invention are used, at least two surface plasmon resonance bands of the anisotropic metal nanoparticles are excited by excitation and emission amplification The nanostructure of the metal-dielectric core-shell can be expected to have a local electric field enhancement effect locally formed on the surface of the metal nanoparticles by always separating the light emitting material by the thickness of the dielectric shell, It is possible to maximize the increase of the luminescence intensity. Also, the light emitted from the light emitting material is strongly scattered by the anisotropic metal nanoparticles, so that light extraction from the light emitting material to the outside can be facilitated, and the efficiency of the light emitting device can be expected to be improved.;
