摘要：

Transparent and nearly colorless ferroclectric-ferroelastic beta'-Tb-2(MoO4)(3) (TMO) single crystals have been grown by the Czochralski (CZ) method. The single crystal structure was investigated by X-ray powder diffraction and was shown to be a single phase with the structure similar as the beta'-Gd-2(MoO4)(3) crystal. The optical transparency of the TMO crystal has been measured and the crystal is almost transparent in the visible and near infrared regions. The defects of TMO crystal were evaluated by etching technique and the ferroelectric domain structures were observed by an optical microscope. A high-resolution X-ray diffraction analysis demonstrates that the as-grown TMO crystal possesses relatively high optical quality. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
