Sythesis of pure phase Cu3PS4 and Cu6PS5cl for semiconductor applications

<p>We have achieved the first reported pure phase synthesis of two new nanoparticle materials, Cu3PS4 and Cu6PS5Cl. We have achieved this through learning about the potential reaction pathways that CuCl2, P2S5, and 1-dodecanethiol can take. This study has shown that the key variable to control is the state of the phosphorus source when the CuCl2 is added. If P2S5 is added together with the CuCl2 to dodecanethiol then the reaction will follow a path to Cu3PS4, but if it is dissolved in dodecanethiol prior to the addition to CuCl2 then the reaction will produce Cu6PS5Cl. The formation of these two different phases can occur simultaneously, yet we have found sets of conditions that manipulate the reaction system to form each phase exclusively. These nanoparticles could have broad semiconductor or solid electrolyte applications.</p> <nb:citations><p><i><strong>RSC Adv.</strong></i>, 2018,<strong>8</strong>, 34094-34101 </p></nb:citations>

本研究首次实现了两种新型纳米颗粒材料Cu₃PS₄与Cu₆PS₅Cl的纯相合成。本次合成通过系统探究氯化铜(CuCl₂)、五硫化二磷(P₂S₅)与1-十二硫醇的潜在反应路径得以完成。研究表明，添加氯化铜时调控磷源的状态为核心变量：若将五硫化二磷与氯化铜一同加入十二硫醇中，反应将沿生成Cu₃PS₄的路径进行；若预先将五硫化二磷溶解于十二硫醇后再加入氯化铜，则反应会生成Cu₆PS₅Cl。尽管两种物相可同时形成，但本研究已筛选出可精准调控反应体系、仅生成单一物相的反应条件。该类纳米颗粒在半导体与固体电解质领域均具备广阔的应用前景。<br><strong>参考文献：</strong><i>RSC Adv.</i>, 2018, <strong>8</strong>, 34094-34101
