采用反胶束法在室温下可控制备了单晶硫酸钙纳米管。这些纳米管具有约20 nm的直径和约420 nm的长度。XRD曲线表明，所获得的纳米管是端心单斜相，晶格参数为a = 6.284埃，B = 15.193埃和c = 5.680埃，这与JCPDS卡号33-0311中报道的值一致。对硫酸钙纳米管光学性质的研究表明，硫酸钙纳米管具有不同于块状硫酸钙纳米管的光学性质。通过控制反应条件，可以得到结晶性较好的纳米棒。本文还讨论了该形成过程的机理。(C)2008 Elsevier B. V.保留所有权利。
Single crystal calcium sulfate nanotubes are controllably prepared via a facile reverse micelles method at room temperature. These nanotubes have diameters of about 20 nm and lengths of about 420 nm. XRD curves indicate that as-obtained nanotubes is end-centered monoclinic phase with lattice parameters of a = 6.284 angstrom, b = 15.193 angstrom and c = 5.680 angstrom, which is consistent with the values reported in JCPDS card no. 33-0311. Study on the optical properties of as obtained nanotubes shows that calcium sulfate nanotubes possess different optical properties from bulk counterpart. When reaction condition is controlled, nanorods with better crystallinity are obtained. A mechanism of the formation process is also discussed. (C) 2008 Elsevier B.V. All rights reserved.
