Description
Summary:Red and green rare‐earth ion (RE3+) (RE = Eu, Tb):MgLa2V2O9 micro‐powder phosphors were produced utilizing a standard solid‐state chemical process. The X‐ray diffraction examination performed on the phosphors showed that they were crystalline and had a monoclinic structure. The particles grouped together, as shown in the scanning electron microscopy (SEM) images. Powder phosphors were examined using a variety of spectroscopic techniques, including photoluminescence (PL), Fourier‐transform infrared, and energy dispersive X‐ray spectroscopy. Brilliant red emission at 615 nm (5D0 → 7F2) having an excitation wavelength (λexci) of 396 nm (7F0 → 5L6) and green emission at 545 nm (5D4 → 7F5) having an λexci = 316 nm (5D4 → 7F2) have both been seen in the emission spectra of Tb3+:MgLa2V2O9 nano‐phosphors. The emission mechanism that is raised in Eu3+:MgLa2V2O9 and Tb3+:MgLa2V2O9 powder phosphors has been explained in an energy level diagram. Eu3+& Tb3+: MgLa2V2O9 phosphors were synthesized by conventional solid‐state reaction method. Eu3+: MgLa2V2O9 phosphors exhibits bright red emission at 615 nm and Tb3+: MgLa2V2O9 powder phosphors exhibits bright green emission at 545 nm.
