Visible photoluminescence measurements regarding the nitrogen gas flow reveal a large emission band centered at 450 nm for a sample deposited under a 2 sccm flow. A special attention is paid to the origin of such an emission at high nitrogen concentration. Different emitting centers are suggested in Ce doped SiO x N y films (e.g. band tails, CeO 2, Ce clusters, Ce 3+ ions), with different activation scenarios to explain the luminescence.
