A green phosphor for a plasma display panel has improved color purity, improved lifespan, and improved discharge stability. The green phosphor comprises a core including at least one first phosphor material selected from the group consisting of Zn2SiO4 : Mn, (Zn, A)2SiO4 : Mn (A is an alkaline earth metal), (Ba, Sr, Mg)O.alphaAl2O3 : Mn (alpha is an integer in a range of 1 to 23), and MgAlxOy : Mn (x is an integer in the range of 1 to 10, and y is an integer in a range of 1 to 30), and a coating layer including a second phosphor which is present on the surface of the first phosphor, and which is at least one selected from the group consisting of LaMgAlxOy : Tb : Tb (x is an integer in the range of 1 to 14, and y is an integer in the range of 8 to 47), ReBO3 : Tb (Re is a rare earth element selected from the group consisting of Sc, Y, La, (Ce, and Gd), and (Y, Gd)BO3 : Tb.
