Introduction to Metal-Nanoparticle Plasmonics

Based on a popular article in Laser and Photonics Reviews, this book provides an explanation and overview of the techniques used to model, make, and measure metal nanoparticles, detailing results obtained and what they mean. It covers the properties of coupled metal nanoparticles, the nonlinear optical response of metal nanoparticles, and the phenomena that arise when light-emitting materials are coupled to metal nanoparticles. It also provides an overview of key potential applications and offers explanations of computational and experimental techniques giving readers a solid grounding in the field.

From theory to applications, this book provides a thorough introduction to current research in the optical properties of metal nanoparticles

Based on a popular article in Laser & Photonics Reviews, this book provides an explanation and overview of the techniques used to model, make, and measure metal nanoparticles, detailing and interpreting results. It also covers the properties of coupled metal nanoparticles, the nonlinear optical response of metal nanoparticles, and the phenomena that arise when light-emitting materials are coupled to metal nanoparticles.

Emphasizing fundamental physical understanding throughout—and offering explanations of computational and experimental techniques supporting this basic understanding—Introduction to Metal-Nanoparticle Plasmonics gives readers a solid grounding in the field.

Beginning with an introduction that covers the excitement surrounding the topic and the long history behind it, the book then:

• Describes analytical and numerical methods for calculating and understanding plasmon resonances in metal nanoparticles
• Explains top-down lithographic methods and bottom-up chemical methods for fabricating metal nanoparticles and their assemblies
• Illustrates experimental methods for characterizing plasmon resonances in metal nanoparticles
• Covers coupled plasmon resonances in assemblies of metal nanoparticles
• Discusses nonlinear optical properties of metal nanoparticles
• Explains how plasmons in metal nanoparticles can interact with nearby light-emitting material
• Presents a selection of potential applications of plasmons in metal nanoparticles
  An ideal introduction to current research in the optical properties of metal nanoparticles, Introduction to Metal-Nanoparticle Plasmonics will appeal to graduate students, postdoctoral researchers, and advanced undergraduate students looking for a deeper scientific understanding of the field.
