Abstract

A new nitridolithosilicate La4Ba3Li3Si9N19 was synthesized by the flux method. The La4Ba3Li3Si9N19:Pr3+ phosphor shows a narrow-band red emission peaking at 640 nm with an fwhm of 50 nm when excited under near-UV light.

Abstract

We report a novel narrow-band blue emitting phosphor Sr7.92Mg7Si9N22:0.08Eu2+. The crystal structure of Sr8Mg7Si9N22 is composed of corner-sharing and edge-sharing [SiN4] tetrahedra and distorted square-pyramid [MgN5] polyhedra. Under 350 nm excitation, Eu2+ doped Sr8Mg7Si9N22 emits narrow-band blue light with maximum intensity at 450 nm and a fwhm of 38 nm.
