Abstract

Time-resolved photoluminescence has been employed to study carrier relaxation dynamics of Eu3+ clusters in GaN. The results indicated that at least two types of Eu3+ clusters formed in the host, which show the similar lifetime of 5D2, 5D1 and 5D0 upper state levels but give quite different red emission intensity.
