Crystal growth and luminescence properties of In6WO12

Abstract Single crystals of indium tungstate In 6 WO 12 have been grown by chemical vapor deposition using TeCl 4 as a transport agent. Isometric as well as octahedral-shaped transparent crystals are obtained with a size attaining 2 mm. The luminescence of both single crystals and powder samples has been investigated. On the basis of a comparison with Y 6 WO 12 , the green emission is ascribed to charge transfer transitions within isolated octahedral tungstate groups.
