Abstract

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)
