Abstract
Provided is a novel CaS-based phosphor with which chemical reactions can be inhibited even if said CaS-based phosphor is heated with a heterogeneous material. This phosphor includes: a crystalline parent material represented by the composition formula CaSrS.yZnO (in the formula, 0≦x<1, 0<y≦0.5); and a luminescent center.
