Abstract

Ag(0)x–Mn3O4 nanocomposite layers have been obtained under “mild” chemical conditions at room temperature by treating the surface of a solution of a mixture of AgNO3 and Mn(NO3)2 salts with ammonia gas. These layers consist of microglobules with a unique jellyfish-like morphology. The size and shape of these microglobules, as well as the density of their arrangement at the solution–air interface, are determined by the time of treatment with ammonia gas. Their comprehensive study was carried out by FESEM, TEM, HRTEM, SAED, XRD, and EDX methods and Raman and FT-IR spectroscopies. A hypothetical model is proposed to explain the formation of jellyfish-like microglobules. It was found that layers of these microglobules can be used as SERS substrates, allowing a signal amplification factor of 107 times to be achieved.

NH3蒸汽†在Ag(i)和Mn(ii)硝酸溶液表面形成水母状Ag(0) x-Mn3O4微球
用氨气处理AgNO3和Mn(NO3)2盐混合溶液的表面,在室温下“温和”的化学条件下获得了Ag(0) x-Mn3O4纳米复合层。这些层由微球组成,具有独特的水母状形态。这些微球的大小和形状,以及它们在溶液-空气界面上的排列密度,是由氨气处理的时间决定的。通过FESEM、TEM、HRTEM、SAED、XRD、EDX等方法以及拉曼光谱和FT-IR光谱对其进行了全面的研究。提出了一个假设模型来解释水母状微球的形成。研究发现,这些微球层可以用作SERS底物,使信号放大系数达到107倍。
