Thermally stable and color-tunable bi-activated (Dy³⁺/Eu³⁺) alkaline earth metasilicate phosphor for luminescent devices.

ABSTRACT: A solid-state reaction methodology has been adopted to synthesize Dy³⁺ (dysprosium)/Eu³⁺ (europium) co-activated Na₄Ca₄Si₆O₁₈ (NCMS) phosphors. The structural, morphological, and luminescence characteristics of the prepared materials have been investigated. The phase purity of the material was confirmed by X-ray diffraction (XRD) by comparing the diffraction peaks with the JCPDS standard pattern (JCPDS card no. 75-1687). The photoluminescence (PL) spectra of NCMS phosphors activated with Dy³⁺ and co-activated with Dy³⁺ (sensitizer)/Eu³⁺ (activator) ions were investigated. The as-prepared NCMS phosphors co-activated with Dy³⁺/Eu³⁺ ions were excited with near-ultraviolet l
