Coated nano particle and electronic device using the same

#This application claims the benefit of Korean Patent Application No. 10-2005-0040675, filed on May 16, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

#1. Field of the Disclosure

#The present disclosure relates to a nano particle used as an illuminator in an electronic device, and more particularly, to a nano particle coated with a material having a lower index of refraction than that of the nano particle on the surface of the nano particle, for improving the luminous efficiency of the electronic device.

#The above and other features and advantages of the present invention will be described in detailed exemplary embodiments thereof with reference to the attached drawings in which:

#FIG. 1 is a schematic view illustrating that an illuminator absorbs light emitted from a light source, and emits light externally in accordance with the conventional technology;

#FIG. 2 is a schematic view illustrating that a coated nano particle fabricated according to an embodiment of the present invention which is dispersed in a matrix;

#The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

#The present invention consists of a nano particle for absorbing and emitting light, and a nano particle coated with a material having a lower index of refraction than that of the nano particle.

#FIG. 3 illustrates a process wherein a coated nano particle of the present invention absorbs light emitted from a light source, and emits light externally. The action of the coated nano particle of the present invention will be explained hereafter.
