AB  - Lanthanide (Ln) activated phosphors are a major topic in both basic and applied science. The trivalent europium ion (Eu3+) is well recognized for its intense luminescence in the orange/red spectral region, making it useful for a wide range of applications. Because Eu3+ has an even number of electrons in its 4f shell ([Xe]4f 6 ), the ion has non-degenerated ground (7F0) and excited (5D0) energy states, as well as non-overlapping 2S+1LJ multiplets, resulting in emission spectra that are predictable in relation to the host material site symmetry. The solid-state reaction synthesis method was used to make a set of five Eu-doped YxLu1- xNbO4 samples (x=0–1) with a fixed Eu concentration (5%). All the structures crystallize as beta-Fergusonite, in which the Eu ion replaces the Y or Lu ion in a large, low-symmetry octahedron. The excitation and emission spectra of the Eu3+ ion in all composition hosts show characteristic f-f transitions from which Stark energy levels were calculated. Specific features and energy positions of the distinctive 5D0→7F1 magnetic dipole transition were determined when measured with higher resolution and spectra deconvolution was utilized. The maximum ΔE splitting of the 7F1 manifold's Stark splitting and the asymmetry ratio R all show Y/Lu content-dependent trends. Calculations based on Judd-Ofelt theory were utilized to determine specific quantities. The lowest non-radiative deexcitation rate was observed with x = 1, resulting in the conclusion that LuNbO4 is a better host-matrix for Eu3+ emission than other compositions.
