Doping graphene with gold improves its performance as a UV LED electrode

Researchers from Korea developed a new gold-doped graphene based transparent and current-spreading electrode (TCSE) for UV LEDs. Graphene was already studied as a conductive layer for UV LEDs, and now it turns out that doping it with gold improves the performance. A gold-doped graphene LED features about 20% more emission compared to an ITO LED.
UV (300-400nm) LEDs are useful in several applications such as germicidal instrumentation, biological agent identification, chemical sensing, fluorescence excitation, and optical data storage. UV LEDs can also be used to emit white light (through phosphorescence).
