Blue-light excitable, green-light emitting Ba3(Sc1−xHox)4O9 phosphors were successfully synthesized in the single-phase form by a melt synthesis method for the first time. These phosphors show sharp green light emission under blue light (455 nm) excitation. The principal green light emission peak observed at 555 nm corresponds to the transition from 5F4 and 5S2 to the 5I8 energy level of Ho3+.
