Disclosed is a method for preparing a fluorescent substance, which is represented by the formula M1-zEuzSiaObNc (M=Sr1-x-yBaxCay, 0=x=0.5, 0=y=0.2, 0<z=0.3, 2=a=2.5, 1.5=b=2, and 2=c=2.5), and the present invention provides the method for preparing a nitride-based fluorescent substance comprising the following steps: a preliminary firing step further comprising a first firing step of creating a first firing product by mixing and firing a first precursor group including an M precursor and a first silicon precursor, and a second firing step of creating a second firing product by mixing and firing a second precursor group including an Eu precursor and a second silicon precursor; and a secondary firing step of mixing and firing the first firing product and the second firing product. |
