Abstract:
The invention relates to a light emitting device, especially a LED comprising a green emitting material of the composition Sr5−y−z−aMySi23−xAl3+xOx+2aN37−x−2a:Euz:Cez1. This material has been found to have a narrow emission in the green wavelight range together with a good producibility and stability.
