摘要

The present disclosure provides a (Ba1−z,Srz)3MgSi2O8:Eu2+ based phosphor with high emission quantum efficiency. Specifically, the present disclosure provides a blue light emitting phosphor including: a (Ba1−z,Srz)3MgSi2O8 based crystal where z satisfies 0≦z<1 and a (Ba1−z,Srz)MgSiO4 based crystal where z satisfies 0≦z<1 as a host crystal; and Eu2+ as a luminescent center.
