Abstract:
Examples of the present invention relate to a phosphor plate composition having a wide emission region while improving luminance. The composition comprises: yttrium aluminum garnet (YAG) or gadolinium yttrium aluminum garnet ((Gd,Y)AG) phosphor powders doped with any one dopant selected from cerium (Ce), gadolinium (Gd) and neodymium (Nd); and a sintering agent of any one selected from lithium fluoride (LiF), magnesium oxide (MgO) and spinel (MgAl2O4).
