Synthesis, structure and properties of a calcium oxonitridosilicate phosphor showing green or red luminescence upon doping with Eu 2+ or Ce 3+

This is the authors' abstract. We don't add key points for this paper.

The new phase Li x Ca 16−x Si 17 N 32−x O 2+x is an easy to make derivative of the so-called Ca 16 Si 17 N 34 and a promising phosphor when doped with Eu 2+ or Ce 3+ .
