Melt-quenching synthesis and spectral tuning of a new green-emitting phosphor Ba₁₀Y₂₆Si₁₆O₈₁:Eu²⁺

Abstract

A new green-emitting phosphor Ba₁₀Y₂₆Si₁₆O₈₁:Eu²⁺ was successfully synthesized via a melt-quenching technique. The crystal structure of the Ba₁₀Y₂₆Si₁₆O₈₁:Eu²⁺ phosphor was confirmed by single-crystal X-ray diffraction (XRD) analysis. The photoluminescence (PL) characterization revealed that the Ba₁₀Y₂₆Si₁₆O₈₁:Eu²⁺ phosphors exhibit yellowish green emission peaking at about 540 nm under near-UV (n-UV) irradiation. The emission spectra can be tuned by the incorporation of Mg²⁺ ions.
