Electroluminescent Device Made of Diamond

Abstract
A diamond light-emitting device was fabricated using boron-doped epitaxial film and a Schottky junction. The emission was white with a spectrum which was quite broad and centered at 530 nm. This spectrum was found to be similar to the spectrum obtained by cathodoluminescence from the boron-doped epitaxial film. The emission is considered to be caused by the injection electroluminescence and the color center named “Band-A” is considered to be the emitted center.
