NER: Generic Production of Nanoparticles in Plasma Microreactors

在等离子体微反应器中生产纳米颗粒这个项目的重点是使用大气等离子体微反应器从气态前体中生产半导体和金属纳米颗粒。 通过在还原条件反应区中的停留时间来实现尺寸控制，同时通过微等离子体中的颗粒充电来限制凝聚。 窄分布的纳米粒子在1- 3 nm的大小制度的生产，其光电和磁性能的特点。将不同材料的带相反电荷的纳米颗粒组合以形成具有新颖性质的颗粒对。这种新的合成技术简单、便宜，但它能产生高质量的纳米颗粒。 它提供了在纳米级的各种材料与新颖的光学，电学和磁学性能的轻松访问。 例如，硅纳米粒子可以产生红色、绿色或蓝色光，有望与硅电子器件集成，以提高通信速度。 此外，具有不同性质的纳米颗粒可以组合以产生能够自组装并具有附加功能的纳米材料，例如磁发光颗粒对。

Generic Production of Nanoparticles in Plasma MicroreactorsThis project focuses on using atmospheric plasma micro-reactors for the generic production of semiconductor and metal nanoparticles from gaseous precursors. Size control is accomplished by residence time in the reducing-conditions reaction zone while simultaneously limiting coagulation by particle charging in the micro-plasma. Narrowly-distributed nano-particles in the 1-3nm size regime are produced, and their optoelectronic and magnetic properties are characterized. Oppositely-charged nano-particles of dissimilar materials are combined to form particle pairs with novel properties. The new synthesis technique is simple, inexpensive, and yet it produces high quality nanoparticles. It offers easy access to a variety of materials at the nanoscale with novel optical, electrical, and magnetic properties. For example, Si nanoparticles can be made to produce red, green, or blue light, promising integration with silicon electronics to increase communication speeds. Also, nanoparticles with different properties may be combined to produce nanomaterials capable of self-assembly with added functionality, for example, magnetic-luminescent particle pairs.
