Uniform orange‐to‐red spherical phosphors of Sr 2 P 2 O 7 : Ce 3+ , Mn 2+ have been synthesized by the co‐precipitation method and characterized by X ‐ray powder diffraction, scanning electron microscopy, and photoluminescence spectroscopy. The results indicate that the morphology, size, and photoluminescence properties of Sr 2 P 2 O 7 : Ce 3+ , Mn 2+ phosphors can be effectively controlled by the reaction and the sintering temperatures. Energy transfer from Ce 3+ to Mn 2+ in Sr 2 P 2 O 7 phosphor was observed from photoluminescence spectra of Sr 2 P 2 O 7 : Ce 3+ , Sr 2 P 2 O 7 : Mn 2+ , and Sr 2 P 2 O 7 : Ce 3+ , Mn 2+ . Moreover, based on a self‐assembly process, a possible formation mechanism for the spherical phosphors is proposed. The uniform phosphor spheres obtained in this work exhibit great potential for high‐resolution display devices such as light emitting diodes.
