Photoluminescence and energy transfer properties of a novel molybdate KBaY(MoO4)3:Ln3+ (Ln3+ = Tb3+, Eu3+, Sm3+, Tb3+/Eu3+, Tb3+/Sm3+) as a multi-color emitting phosphor for UV w-LEDs

A novel series of KBaY(MoO₄)₃:Ln³⁺ (Ln³⁺ = Tb³⁺, Eu³⁺, Sm³⁺, Tb³⁺/Eu³⁺, Tb³⁺/Sm³⁺) as multi-color emitting phosphors for UV w-LEDs has been prepared and investigated.
