Photoluminescence properties of solid-state Tb³⁺ doped NaY(MoO₄)₂

Abstract

A series of Tb³⁺ doped NaY(MoO₄)₂ are synthesized by a solid-state reaction at 550 °C for 4 h, and their luminescent properties are investigated. The phase formation is carried out with X-ray powder diffraction analysis, and there is no other crystalline phase except NaY(MoO₄)₂. NaY(MoO₄)₂:Tb³⁺ can produce the green emission under 290 nm radiation excitation, and the luminescence emission peak at 545 nm corresponds to the ⁵D₄→⁷F₅ transition of Tb³⁺. The emission intensity of Tb³⁺ in NaY(MoO₄)₂ is enhanced with the increase of Tb³⁺ concentration, and there is no concentration quenching effect. The phenomena are proved by the decay curves of Tb³⁺. Moreover, the Commission International de I’Eclairage (CIE) chromaticity coordinates of NaY(MoO₄)₂:Tb³⁺ locate in the green region.
