Abstract
The present disclosure provides a (Ba,Sr)MgSiO:Eubased phosphor with high emission quantum efficiency. Specifically, the present disclosure provides a blue light emitting phosphor including: a (Ba,Sr)MgSiObased crystal where z satisfies 0≦z<1 and a (Ba,Sr)MgSiObased crystal where z satisfies 0≦z<1 as a host crystal; and Euas a luminescent center.
