Luminescence spectra of Eu‐doped GaN with varying Eu concentration and V/III ratio were investigated. Eu‐related luminescence originating from the 5 D 0 – 7 F 2 transition of Eu 3+ was observed at about 622 nm. The luminescence basically consisted of three peaks, and the relative intensity of the three peaks was affected by the Eu concentration and the V/III ratio. These results indicate that the Eu incorporation site is very sensitive to the Eu concentration and the V/III ratio. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
