U.S.-Bulgarian Cooperative Research: Laser Assisted Modification of Nanocomposite Thin Films

这是一个美国-保加利亚的合作研究项目，将调查是否有可能利用磁控管共溅射法以可控和可再现的方式获得和修改含有各种金属纳米团簇的薄介电膜，这些金属纳米团簇具有均匀的窄团簇尺寸分布。 主要研究人员是来自佛罗里达新学院的Mariana Sendova博士和来自保加利亚太阳能中心实验室的Marushka Sendova-Vassileva博士。 本研究的目的是使用现有的溅射和脉冲激光器在各种电介质基质中生长金属纳米团簇。 这种纳米复合材料具有有趣的光学和电光特性，在不同类型的光学器件中具有潜力。 本研究结合了磁控共溅射和激光辅助改性的优点，为快速发展的纳米材料和纳米技术领域提供了新的实验数据。这个数学研究项目实现了汇集美国和中欧/东欧领先专家的计划目标，在平等，互惠和互利的基础上，在强烈的共同利益和能力领域联合收割机互补努力和能力。

This is a U.S.-Bulgarian cooperative research project that will investigate the possibilities of obtaining and modifying, in a controlled and reproducible way, thin dielectric films containing various metal nanoclusters with a homogeneous narrow cluster size distribution using magnetron co-sputtering. The principal investigators are Dr. Mariana Sendova from the New College of Florida and Dr. Marushka Sendova-Vassileva from the Central Laboratory for Solar Energy in Bulgaria. The objective of this research is to grow metal nano-clusters in various dielectric matrices using existing sputtering and a pulsed laser. Such nanocomposites have interesting optical and electro-optical properties which will have potential in different types of optical devices. This research will contribute new experimental data to the rapidly developing area of nanomaterials and nanotechnology as it combines the advantages of magnetron co-sputtering together with those of laser-assisted modification of thin films. This project in mathematics research fulfills the program objectives of bringing together leading experts in the U.S. and Central/Eastern Europe to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.
