Abstract

A new luminescent material, Eu³⁺ activated Ca₃Sr₃(VO₄)₄, was investigated. This compound shows a strong red emission centered at 618 nm under near-UV light with two distinct absorption bands; charge transfer state of VO₄^3- and f-f transitions of europium ions. As the europium concentration is increased, an additional red-emitting phosphor, EuVO₄, which is known to be a prominent luminescent material in the near-UV region can be traced. The UV excited luminescent properties of this material may find application in the production of red phosphors for white light-emitting diodes.
