Title:
INORGANIC SCATTERING FILM HAVING HIGH LIGHT EXTRACTION PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2013/008982
Kind Code:
A1
Abstract:
The present invention relates to an inorganic scattering film having high light extraction performance, and more particularly, to an optical thin film having high light extraction effects caused by forming an inorganic particle film including a void at an interface of a light emitting device or on a transparent substrate, and to a method for manufacturing same. A method for manufacturing a nano-size particle powder according to the present invention may be applied to many types of complex oxide powder composites since the size and shape of composite powders can be controlled, and an inorganic scattering film including the powder has high light extraction effects caused by the inorganic particle scattering film having the void, and can thus be applied to image display devices, lighting elements, solar cells, and the like.
