    • The present invention relates to a novel method for manufacturing a tapering tin sulfide nanorod via a solution synthesis method and, more particularly, to a method for manufacturing a tin sulfide nanorod induced by a self-catalyst and grown by a solution-liquid-liquid-solid (SLLS) method. The manufacturing method according to the present invention can be used for the materials of photoelectronic devices, photovoltaic cells or holographic optical devices because tin sulfide can be manufactured without adding another catalyst, process steps can be reduced, as the synthesis of bismuth (Bi) or gold (Au) nanoparticles is not necessary, and a high-crystallinity tapering nanorod can be manufactured in short time at low costs. Moreover, the method for manufacturing a tin sulfide (SnS) nanorod according to the present invention can be applied to use tin (Sn) or Indium (In) as a catalyst in not only tin sulfide (SnS) but also another system via a mechanism of tin (Sn), which has excellent reactivity to be unstable and is difficult to be synthesized into nanoparticles, functioning as a self-catalyst at an initial point of reaction. The method for manufacturing tin sulfide (SnS) according to the present invention can be provided as a novel method for growing a nanoline by disclosing an SLLS growth mechanism.
    • 本发明涉及一种通过溶液合成方法制造锥形锡硫化物纳米棒的新方法,更具体地涉及一种由自催化剂诱导并通过溶液 - 液 - 液 - 液相生长的硫化锡纳米棒的制造方法, 固体(SLLS)方法。 根据本发明的制造方法可以用于光电子器件,光伏电池或全息光学器件的材料,因为可以在不添加另一种催化剂的情况下制造硫化锡,可以减少工艺步骤,因为铋(Bi)或 金(Au)纳米颗粒是不必要的,并且可以在短时间内以低成本制造高结晶度锥形纳米棒。 此外,根据本发明的硫化锡(SnS)纳米棒的制造方法可以应用于使用锡(Sn)或铟(In)作为不仅硫化锡(SnS)的催化剂,而且还可以通过机构使用另一种体系 的锡(Sn),其反应性优异,不稳定,难以合成纳米粒子,在起始反应时起自催化作用。 可以提供根据本发明的硫化锡(SnS)的制造方法,作为通过揭示SLLS生长机制来生长纳米脂肪酸的新方法。
