Abstract

Recently, vanadium oxide based materials have been intensively studied due to their unique structural, optical, electrical and magnetical properties. In this work, LiZnVO4ceramics were obtained by the conventional solid-state reaction method or by the sol-gel technique. We report on the compositional and morphological characterization of LiZnVO4 samples, as well as on the influence of the preparation method on the photoluminescence and dielectric properties. The highest emission intensity was attained for the sol-gel LiZnVO4 powder thermally treated at 600 °C, while the best microwave dielectric properties (εr ~ 7.5 and Q×f ~ 37900 GHz) were achieved for the conventional LiZnVO4 resonator sintered at 700 °C..
