Abstract

In this study, we synthesized GdVO₄:5%Eu³⁺ using a straightforward combustion method. The structures, chemical composition, and optical properties of this material were analyzed through X-ray diffraction (XRD), energy-dispersive X-ray (EDX), and photoluminescence (PL) spectra. The emission spectra, observed under 470 nm excitation, correspond to the ⁵D₀–⁷F_J (J = 0–4) transition of the Eu³⁺ ion, resulting in red emission within the 590-700 nm region, aligning with the light absorption spectrum of plants. WLED devices were fabricated using GdVO₄:5%Eu³⁺ and YAG:Ce³⁺ powders towards agricultural purposes. The color coordinates of the resulting WLED were (0.319, 0.323), close to the standard white emission coordinate (0.333, 0.333).
