Would someone please tell me what an extinction spectrum refers to? e.g. for plasmonic gold nanoparticles. Is it the same thing as reflection, absorption, or transmission spectrum? Something else?
An Extinction Spectrum refers to the measurement of light absorption and scattering by a material as a function of wavelength. It is often used in the study of plasmonic gold nanoparticles, which exhibit unique optical properties due to their small size and shape.
Plasmonic Gold Nanoparticles are typically created through a process called chemical synthesis, where gold ions are reduced to form small particles. The size and shape of these particles can be controlled to produce different optical properties.
Plasmonic Gold Nanoparticles have a unique ability to interact with light at the nanoscale. They can enhance the absorption and scattering of light, making them useful for applications such as biomedical imaging and sensing.
The Extinction Spectrum of Plasmonic Gold Nanoparticles is highly dependent on their size and shape. As the size of the nanoparticles decreases, the peak of the spectrum shifts towards shorter wavelengths, resulting in a blue shift.
Plasmonic Gold Nanoparticles have a wide range of potential applications, including biosensing, drug delivery, and cancer therapy. They can also be used in the development of new optical devices, such as plasmonic sensors and photovoltaic cells.
