The synthesis of a new garnet, Er₃Li_0.275Nb_0.275Ga_4.45O₁₂ (ErLNGG), by solid-state reaction, is reported. A comparison of the fluorescence spectra of Er³⁺ in ErLNGG, Er-doped (0.1 at.%) calcium lithium niobium gallium garnet (CLNGG), and Er(50 at.%):CLNGG is presented. The narrowing of luminescence lines suggests an ordering of the partially disordered CLNGG with the increase of erbium concentration.
