[ad_1] Surface-enhanced Raman scattering greatly magnifies the weak light signals associated with Raman scattering, allowing for the detection of trace chemical compounds. This effect is achieved when molecules are in contact with metal nanoparticles, causing plasmons to be created on the surface of the metal. This led to the development of surface-enhanced Raman spectroscopy (SERS), […]
[ad_1] Light can be scattered when it interacts with a molecule, causing it to emit a new photon at the same frequency, known as elastic scattering. Inelastic scattering, such as Raman scattering, occurs when the emitted photon has a lower or higher frequency. Raman scattering can be used to determine the composition of a material […]
[ad_1] Mie scattering is the scattering of radiation by spherical particles, with formulas working best when particles are similar in size to the wavelength. It can be used to determine particle size and composition, and is used in meteorology and biology. Gustav Mie developed the formulas in 1900. Mie scattering is how spherical particles scatter […]
[ad_1] Electromagnetic dispersion causes light to refract or bounce off objects, creating color. Rayleigh diffusion explains why the sky is blue. Mie theory deals with larger scattering centers. Elastic and inelastic scattering have various applications in fields such as astrophysics and medical technology. Electromagnetic dispersion is the physical effect of an electromagnetic wave, such as […]
[ad_1] Rayleigh scattering is when light is scattered by small particles smaller than the wavelength of light. It occurs in gases, liquids, and solids and is used in optical fibers. The sky appears blue due to the scattering of blue light. Rayleigh scattering is a physical phenomenon in which light is scattered in different directions […]
