Nitride-Based Ultraviolet LED with an Ultraviolet Transparent Contact

TECHNOLOGY SUMMARY

This (Al, Ga, In)N ultraviolet light-emitting diode (UVLED) includes a UV-transparent contact, which significantly enhances the light extraction and quantum efficiency of these devices. This technology also eliminates mirrors and/or mirrored surfaces in order to reduce internal reflections and minimize light re-absorption by the emitting layer.
