New interesting luminescent a-sialon (M (m/val+) val+ Si 12-(m+n) Al (m+n) O n N (16Àn) ) (M=Ca, Y) materials doped with Ce, Tb, or Eu have been prepared and their luminescence properties studied. These show that Tb and Ce are in the 3+ and Eu in the 2+ state. Low-energy 4f $ 5d transitions are obse
