Beschreibung
Zusammenfassung:	Described are light emitting diode (LED) devices including a combination of electroluminescent and photo-luminescent active regions in the same wafer to provide LEDs with emission spectra that are adjustable after epitaxial growth. The LED device includes a multilayer anode contact comprising a reflecting metal and at least one transparent conducting oxide layer in between the metal and the p-type layer surface. The thickness of the transparent conducting oxide layer may vary for LEDs fabricated with different emission spectra.
