Abstract:
A blue phosphor having an emission peak wavelength different from that of conventional blue phosphors, a method for producing the same, and a high-intensity luminescent device using the phosphor are provided. The phosphor of the present invention is represented by a general formula MeaRebAlcSidOeNf (Me may contain one or more elements selected from Mg, Ca, Sc, Y, and La as second elements, provided that Sr or Ba is contained as an essential first element, and Re may contain one or more elements selected from Mn, Ce, Tb, Yb, and Sm as second elements, provided that Eu is contained as an essential first element), where the composition ratio represented by a, b, c, d, e, and f has the following relations: a+b=1, 0.005
