摘要

In the present work, single-phase yttrium niobium titanate phosphor (YNbTiO6) induced with trivalent europium (Eu3+) ions have been synthesized using a high-temperature solid state reaction (SSR) procedure. The structural phase, morphology and spectroscopic features of the synthesized Eu3+ induced YNbTiO6 (YNT: Eu3+) phosphors have been investigated with the help of various methods of characterization, such as X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and photoluminescent (PLE and PL) studies, respectively. Pure and single-phase formation with orthorhombic structure of the synthesized YNT: Eu3+ phosphor has been confirmed via diffraction profiles. FE-SEM micrograph of the synthesized YNbTiO6 (YNT) sample represents the irregular and agglomerated morphology, with non-uniform particle formation in the micron range. Upon being excited by UV, n-UV, and blue lights, the synthesized YNT: Eu3+ phosphor emits several characteristic peaks of the Eu3+ ions and a dominant emission peak has been observed in the red region (612 nm). Furthermore, the chromaticity coordinates were estimated for the synthesized 1.0 mol% Eu3+ induced YNT phosphor under UV, n-UV and blue excitations, respectively. Hence, the results mentioned above confirm that the synthesized YNT: Eu3+ phosphor could be useful as a red-emitting component for photonic applications.
