Efficient White Light Generation in ZnMoO₄ Phosphors Co-Doped with Eu³⁺ and Dy³⁺

Abstract

Eu³⁺–Dy³⁺ co-doped ZnMoO₄ phosphors were synthesized using a high-temperature solid-state reaction method. The emission spectra were analyzed to determine the Commission Internationale de l’Éclairage (CIE) chromaticity coordinates (x, y), enabling precise evaluation of the emitted color. The results indicate that the luminescence color of the prepared phosphors is strongly dependent on the relative concentrations of Eu³⁺ and Dy³⁺ ions, demonstrating effective tunability of emission characteristics.
