Abstract: A barium-magnesium phosphate-based phosphor is provided to ensure high brightness under 200~400 nm excitation and good chromatic purity, and to be useful for an emitting device for the ultraviolet excitation light emitting diode. A method for manufacturing a barium-magnesium phosphate-based phosphor comprises the steps of: manufacturing a mixture by weighting a barium precursor, magnesium precursor, phosphoric acid precursor, manganese precursor and europium precursor in a range represented by formula 1: Ba_(1-x)Mg_(1-y)P_2O_7:xEu, yMn; drying the mixture at 100~150 °C; oxidizing and heat-treating the dried mixture at 800~1100 °C; and pulverizing the mixture, then reducing and heat-treating the mixture at 800~1100 °C in a reducing atmosphere of 1~20 volume % hydrogen. In the chemical formula 1, 0
