Structure of vanadium-doped lithium disilicate, Li_{2}Si_{2}O_{5} (Ccc2 space group) is studied. This crystalline phase is obtained by annealing of the doped lithium disilicate glass for 4 h at 550°C. X-ray diffraction and X-ray absorption near-edge structure analysis indicate location of vanadium atoms at Si sites. the lattice parameters are found to increase isotropically with increasing vanadium content. the valency of vanadium ions is discussed on the basis of X-ray absorption near-edge structure results.
