Title:
WAVELENGTH CONVERTING PARTICLE, METHOD FOR MANUFACTURING WAVELENGTH CONVERTING PARTICLE, AND LIGHT EMITTING DIODE CONTAINING WAVELENGTH CONVERTING PARTICLE
Document Type and Number:
WIPO Patent Application WO/2016/072803
Kind Code:
A1
Abstract:
Provided are a wavelength converting particle, a method for manufacturing a wavelength converting particle, and a light emitting diode containing a wavelength converting particle. The wavelength converting particle comprises an organic-inorganic hybrid perovskite nanocrystal for converting the wavelength of light generated from an excitation light into a certain wavelength. Accordingly, it is possible to optically stabilize and improve color purity and light-emitting performance without changes to the light-emitting wavelength range.
