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.
一种电致发光(EL)装置,其发光层包括涂有有机层的
金属纳米颗粒。涂有有机层的
金属纳米粒子可选择性地移除准分子级的吸收带,而不影响最大吸收或发射波长,从而提高电致发光器件的色纯度和发射效率。
