Searching of new Eu^{2+-activated phosphor in a Na-Sc-Si-O system}

Abstract

In the present study, we have found a new compound in a Na-Sc-Si-O system. The synthesis of the new compound with a high phase purity was achieved when the sample was synthesized with a ratio of Na:Sc:Si = 3:1:3. The Eu2+-activated new compound showed a broad emission band with a maximum at 530 nm and a broad excitation bands up to 500 nm.
