Abstract: A light-emitting device includes a light-emitting diode having an emissive surface, and a capping layer including an organic solid crystal overlying the emissive surface. The refractive index of the organic solid crystal may be tuned such as through the application of a voltage, current, or stress to improve the light extraction efficiency of the device.
