Abstract:
1. An oxynitride phosphor represented by a general formula of L X M Y O Z N ((2/3)X+(4/3)Y−(2/3)Z) :R (L is Ba. M is Si. O is an oxygen element. N is a nitrogen element. R is Eu. 0.5<x<1.5, 1.5<y<2.5, and 1.5<z<2.5), the oxynitride phosphor having a crystal structure of the orthorhombic system, wherein the at least part of said L is substituted by said R in a molar ratio of (a mix amount of said L and said R):(the amount of said R)=1:0.01 to 1:0.05.
