Abstract

This paper discusses the origin of emission quenching in yttrium orthovanadate codoped with Eu³⁺ and Sb³⁺ ions. Highly crystalline yttrium orthovanadate nanoparticles with chemical composition Y_1-x-yEu_xSb_yVO₄ (x = 0-5.4 mol %, y = 0-2.1 mol %) were prepared using the modified Pechini's method. The particles' structural and morphological properties were studied using X-ray powder diffraction and scanning electron microscopy techniques. Moreover, X-ray photoelectron spectroscopy was used to determine the oxidation state and surface bonding of individual ions in the obtained materials. The photoluminescence spectral and dynamical properties were investigated in detail. The observed Eu³⁺ luminescence depreciation is ascribed to reabsorption mediated by a low-lying Sb³⁺-to-V⁵⁺ metal-to-metal charge transfer state in conjunction with lattice defects absorbing in the visible spectral region.
