摘要	Single crystals of quasi-one-dimensional charge-density-wave conductor blue bronze Tl(0.3)MoO(3) have been grown by electrolytic reduction method using the raw materials Tl(2)CO(3)-MoO(3) with composition around 1:4.3 mol ration. The electrolytic temperature was about 570 degrees C, and electrolytic current was 25 mA during the electrolytic process. By this method, the Tl(0.3)MoO(3) single crystals obtained have a relatively large average size and high quality. Platelet crystals with typical dimensions of 7 x 2 x 1 mm(3) were obtained. The crystal structure is monoclinic with space group C2/m. The parameters of the unit cell of the single crystal are as follows: a = 18.486(6)angstrom, b = 7.555(2)angstrom, c = 10.032(3)angstrom and beta = 118.38(3)degrees. The C-center symmetry of Tl(0.3)MoO(3) crystal is demonstrated by the selected area electron diffraction (SAED) patterns in the transmission electron microscope (TEM). The full-width at half-maximum (FWHM) of the rocking curve of the (201) Bragg peak of the Tl(0.3)MoO(3) was approximately 0.4 degrees. These are evidences that the single crystal is of high quality. The temperature dependence of the resistivity shows that a metal-semiconductor transition occurs near 181 K. (c) 2005 Elsevier B.V. All rights reserved.
