METHOD FOR MANUFACTURING TAPERING TIN SULFIDE NANOROD VIA SOLUTION SYNTHESIS METHOD

摘要

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.;COPYRIGHT KIPO 2014
