摘要：
A phosphor indicated by general formula Me a R b Si c ,Al d N e O f . In the formula: Me has Sr as an essential element thereof and can include one or more types of element selected from Na, Li, Mg, Ca, Ba, Sc, Y, and La; and Re has Eu as an essential element thereof and can include one or more types of element selected from Mn, Ce, Tb, Yb, and Sm. In addition, when a=1-x, b=x, c=(2+2p)x(1-y), d=(2+2p)xy, e=(1+4p)x(1-z), and F(1+4p)xz, parameters p, x, y, and z fulfill the following: 1.620
