Abstract

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.
