Abstract. Facile and effective synthesis strategy is dramatically desirable for basic studies and practical applications of Eu 2+ luminescent materials. In this work, facile chemical lithiation is used for reduction of trivalent Eu 3+ ions into divalent Eu 2+ ions in Eu 1/3 Zr 2 (PO 4 ) 3 crystal structure using nBu-Li solution at room temperature. VUV/Vis luminescence properties, X-ray absorption near edge structure (XANES), and magnetic properties were used to characterize the valence state of Eu ions in crystal structure of host lattice.
