The present disclosure provides a (Ba 1−z ,Sr z ) 3 MgSi 2 O 8 :Eu 2+ based phosphor with high emission quantum efficiency. Specifically, the present disclosure provides a blue light emitting phosphor including: a (Ba 1−z ,Sr z ) 3 MgSi 2 O 8 based crystal where z satisfies 0≦z<1 and a (Ba 1−z ,Sr z )MgSiO 4 based crystal where z satisfies 0≦z<1 as a host crystal; and Eu 2+ as a luminescent center. |
