Formation of Metallic Nanostructures in Organic Matrix by Vapour and Plasma Phase Deposition and its Modification by Swift Heavy Iron Irradiation

近年来，由金属纳米颗粒分散在聚合物基质中的纳米复合材料因其新颖的功能性质而受到人们的极大关注。本研究项目致力于制备含金属的聚合物基纳米复合材料及其在快速重离子辐照下的纳米结构修饰。特别是，我们将争取能够形成具有明确组成的纳米复合材料的方法。为同时沉积金属和聚合物，将并行研究两种无溶剂的中心方法--气相共沉积和等离子体共沉积。这些互补的共沉积技术有望开发出具有所需和优化成分的纳米复合材料，并通过同时研究这两种生产方法来确定新的事实。已经在这方面进行的预备研究证明了上述办法的可行性。还将进行研究，以获得通过离子束照射来定制纳米结构的能力，以便以非常低的额外成本带来量子尺寸效应的新变化。预计将出现一些有用的新量子光学和电子设备。

Recently, there is much interest in nanocomposite materials consisting of metal nanoparticles dispersed in a polymer matrix due to their novel functional properties. This research project is concerned with producing polymer-based metal containing nanocomposites and the nanostructural modifications upon swift heavy ion irradiations. In particular, we will strive for approaches that allow formation of nanocomposites of well defined compositions. Two solvent free central methods of vapor phase codeposition and plasma phase codeposition will be investigated in parallel for simultaneous deposition of metal and polymer. These complimentary codeposition techniques are expected to lead to develop nanocomposite materials with the desired and optimized compositions and to establish new facts by simultaneous studies with the two production methods. Preparatory studies already carried out in this direction have demonstrated the feasibility of the above approaches. Investigations will also be carried out to gain the ability to tailor the nanostructures by ion beam irradiation in order to bring new changes in the quantum size effects at very low additional costs. A number of useful new quantum optical and electronic devices are expected to emerge.
