Abstract

See full text

There is provided a light-emitting device with enhanced luminescence efficiency, which simultaneously exhibits excitation enhancement and emission enhancement of a light-emitting material by controlling two or multiple surface plasmon resonance bands of anisotropic metal nanoparticles to be formed in a near ultraviolet light range and a visible light range and optimizing overlapping of a wavelength of a near ultraviolet or blue light source with an absorption wavelength and an emission wavelength of the light-emitting material. There is also provided a light-emitting device with improved color gamut and luminance, which simultaneously exhibit emission enhancement of different types of light-emitting materials by controlling two or multiple surfaces plasmon resonance bands of anisotropic metal nanoparticles to be overlapped with absorption and emission wavelengths of two or more light-emitting materials having different emission wavelengths from one another.
