We have realized high-efficiency excitonic emission with deep-UV light at room temperature for a (001)-oriented diamond light-emitting diode with an intrinsic diamond layer as an active region. The boron-doped p-type, non-doped intrinsic, and phosphorus-doped n-type ($ p$–$i$–$n$) junction diode structure was formed by applying an optimized homoepitaxial growth technique based on microwave plasma-enhanced chemical vapor deposition. High-performance $ p$–$i$–$n$ junction characteristics were confirmed from current–voltage and capacitance–voltage properties. A strong UV light emission at around 240 nm due to free exciton recombination was observed at a forward current of over 6 mA, while the broad visible light emission from deep levels was significantly suppressed compared to that of reported electroluminescence in diamond $ p$–$n$ junctions.
