A phosphor having increased luminance and lifespan which includes a halide flux of the Group 1 element of the periodic table has a perovskite structure and satisfies the following formula: <paragraph lvl="0"><in-line-formula>MTiO3:(A,B) </in-line-formula>where M is an alkali earth metal, A is a rare earth element, and B is a Group 13 element of the periodic table. The halide flux-containing phosphor shows good luminance and lifespan characteristics compared to conventional phosphors without using sulfur and environmentally harmful cadmium in a host matrix. Therefore, the phosphor is advantageously utilized for various display applications including vacuum fluorescent displays (VFDs) and field emission displays (FEDs).
