Growth of Na0.95K0.05Y(WO4)(2) crystals
Tetragonal scheelite-like single crystals Na0.95K0.05Y(WO4)(2) have been grown in air by using RF-heating Czochralski (CZ) method. Crystal growth was carried out along [1 0 0], [00 1] and [1 0 1] directions. The {1 0 1} facets are strongly exposed. Crystals grown along [100] and [101] directions always show cleavage along {001} faces. The relation of growth habits with structure was discussed. The unit-cell parameters of the undoped crystals were calculated as a = b = 0.5209 nm, c = 1.1290 nm, V = 0.3064 nm(3). Transmittance spectra of the crystals doped with Nd3+ ions have also been included as a first approach to the optical behavior of the grown crystals.
