Silicon nitride/oxynitride-based ceramics are well established as engineering materials in many industrial applications.In the last decade these materials have attracted a high attention due to their ability to serve as a host lattices for phosphors.In this study europium and cerium-doped MgSiN2 and LaSi3N5 have been synthesized from Si/Mg2Si/Si3N4 or LaSi/Si/Si3N4 mixtures doped with Eu2O3,Sm2O3 or CeO2 by direct nitridation.
