Abstract

Blue-light excitable, green-light emitting Ba₃(Sc₁₋_xHo_x)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⁺.
