Abstract

NaY0.99Eu0.01(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.
