Abstract
A nanocomposite material and a method of manufacturing the same are disclosed. The nanocomposite material includes a plurality of nanoparticles coated with a metal oxide, and a matrix of the metal oxide immobilizing the nanoparticles that are dispersed therein. The nanocomposite material is manufactured such that macro- or macro-scale cracks are prevented or effectively prevented, light stability is enhanced over a light-emitting period, and light brightness is improved.
Claims17
A method of manufacturing a nanocomposite material comprising:
- coating surfaces of synthesized nanoparticles with a metal oxide to modify the surfaces of the nanoparticles;
- conducting a sol-gel reaction in a precursor solution in which the surface-modified nanoparticles are mixed with a precursor material of the metal oxide;
- and
- drying the precursor solution to form a solid matrix.
