The synthesis of Nd³⁺ doped lithium lanthanide tetraphosphate (LiLaP₄O₁₂) nanocrystalline powders was presented. Their structure, morphology and spectroscopic properties are determined. The luminescence properties of LiLa_1−xNd_xP₄O₁₂ nanocrystalline powders were studied as a function of concentration of Nd³⁺ ions. The fluorescence branching ratio of ⁴F_3/2 → ⁴I_J transitions were strongly dependent on Nd³⁺ concentration what was associated with self-absorption of the resonant fluorescence R₁ → Z₁ transition. It was found that the fluorescence quenching rate has demonstrated a linear concentration dependence.
