Abstract
Europiumdoped nanocrystals of lithium zinc vanadium oxide LiZnVO4 prepared via the sol–gel method are characterized The Xray power diffraction results reveal that a pure phase is obtained at 500 °C The photoluminescence spectra of LiZnVO4xEu x = 7 mol exhibit emission peaks at 526 597 and 620 nm The emission shifts from bluishgreen to yellow when the doping concentration is increased from 0 to 7 mol due to the emission peak at 620 nm from the 5D0 → 7F2 transition which originated from charge transfer transitions from VO4 3− to Eu3+ ions
