An electroluminescence device having improved luminescence per volt input is provided. The device can include a first electrode, a second electrode, a diamond-like carbon layer electrically coupled to at least one of the first electrode or the second electrode, and a luminescent material electrically coupled to the diamond-like carbon layer, to the first electrode, and to the second electrode, such that upon receiving electrons from the diamond-like carbon layer, the luminescent material luminesces. The diamond-like carbon layer and the luminescent material can be separated by a dielectric material. As the frequency of an introduced alternating current is increased, the level of luminosity of the luminescent material increases, and the voltage required to generate similar levels of luminosity decreases.
