Abstract
We report the increased emission intensity of Ca2KMg2V3O12 by partially substituting the V5+ ion for the P5+ ion. The emission intensity of Ca2KMg2(V0.95P0.05)(3)O-12 was approximately 1.3 times greater than that of Ca2KMg2V3O12. The obtained phosphors were excited and emitted at 360 nm and 520 nm, respectively, and the emission obtained as a greenish white emission. The color coordinates of Ca2KMg2(V0.95P0.05)(3)O-12 were x = 0.377 and y = 0.463.
