摘要：

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