By a solid state reaction of LaN, Eu2O3 and Si3N4, LaSi3N5, La0.9Eu0.1Si3N5-xOx and LaEuSi2N3O2 were prepared at 1900°C for 2h under 1.01 × 106 N m-2 nitrogen pressure. These compounds were identified by X-ray diffraction analysis, and then characterized by means of absorption and luminescence spectroscopies. La0.9Eu0.1Si3N5-xOx was isostructural with LaSi3N5. For only La0.9Eu0.1Si3N5-xOx, we observed a broad emission band with a maximum at 549 nm due to the 4f65d → 4f7 transition of Eu2+. On the other hand, the Eu2+ ion in LaEuSi2N3O2 showed a deep-red emission band at 650 nm.
