Blue-light excitable, green-light emitting Ba 3 (Sc 1¹x Ho x ) 4 O 9 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 5 F 4 and 5 S 2 to the 5 I 8 energy level of Ho 3+ .
