Herein, we report the synthesis of new PtTe multi-crystallite nanoparticles (NPs) in different sizes through an annealing process using new nanostructured Pt-Te organometallic NPs as a single source precursor. This precursor was obtained in a single reaction step using PhTe and HPtCl and could be successfully size controlled in the nanoscale range. The resulting organometallic composite precursor could be thermally decomposed in 1,5 pentanediol to yield the new PtTe multi-crystallite NPs. The final size of the multi-crystallite spheres was successfully controlled by selecting the nanoprecursor size. The sizes of the PtTe crystallites formed using the large spheres were estimated to be in the range of 2.5-6.5 nm. The results provide information relevant to understanding specific mechanistic aspects related to the synthesis of organometallic nanomaterials and nanocrystals based on platinum and tellurium.
在此，我们报告了通过使用新型纳米结构 Pt-Te 有机金属 NPs 作为单源前体制备不同尺寸的新型 PtTe 多晶纳米颗粒 (NPs) 的合成。该前体可以通过 PhTe 和 HPtCl 在单步反应中获得，并可以成功地在纳米范围内进行尺寸控制。所得的有机金属复合前体可以在 1,5-戊二醇中热解以生成新的 PtTe 多晶纳米颗粒。通过选择纳米前体的尺寸，可以成功地控制多晶纳米球的最终尺寸。使用大球形成的 PtTe 晶体的尺寸估计在 2.5-6.5nm 范围内。这些结果提供了与理解基于铂和碲的有机金属纳米材料和纳米晶体合成的特定机理方面相关的信息。
