The luminescence properties of Si,Eu-codoped AlN phosphors were investigated by means of cathodoluminescence. The concentration of Eu was kept constant, while that of Si was varied from 0 to 9.0 at.% using two different Si-source starting powders, Si3N4 and SiC. The luminescence of Eu2+ in AlN is only observed for samples doped with Si. On the other hand, a concentration quenching is observed for samples doped with high amount of Si from Si3N4 while not for those doped from SiC. These results show the importance of Si in the luminescence properties of Eu2+-doped AlN.
