Mg₂TiO₄:Mn deep red emitting phosphor was synthesized by a liquid phase synthesis using urea and PEG. The inhomogeneous and agglomeration of the particle decreased, and fine particle phosphor was obtained. Mg₂TiO₄ phase was preferentially formed and observed at 658 nm and 670 nm under 450 nm excitation.
