A Mn4+-doped BaMg6Ti6O19 red phosphor was synthesized by a solid-state reaction. This phosphor showed red emission with a peak at 660nm because of the 2E→4A2 transition of Mn 4+ upon excitation in the region from near ultraviolet to blue. The specimen doped with 0.1% Mn and synthesized at 1250 °C exhibited the maximum emission intensity. BaMg6Ti6O19:Mn 4+ is a novel red phosphor of titanate, which is the host material.
