Abstract
An electroluminescent (EL) device which has a light emitting layer including metal nanoparticles coated with an organic layer. The metal nanoparticles coated with the organic layer selectively remove an absorption band appearing at an excimer level without affecting a maximum absorption or emission wavelength, thereby enhancing the color purity and emission efficiency of the EL device.
