Tóm tắt

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 5D0–7FJ (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).
