Abstract

NaY_0.99Eu_0.01(WO₄)₂ crystals were grown along 〈101〉 and 〈001〉 directions. Single crystals with high quality can be obtained when they were grown along 〈101〉 direction from a melt with a small deviation from stoichiometric composition. Eu ions exist in two valences in the as-grown crystals, in one valence after annealing only. The fluorescence spectrum shows the Stark splitting of energy levels of Eu ions is in accordance with the site symmetry of S₄.
