Sentences with phrase «plasmon resonance»
"Plasmon resonance" refers to the collective oscillation of electrons in a material when they are stimulated by light or other electromagnetic waves. It occurs when the frequency of the light matches the natural frequency of the electrons in the material, resulting in enhanced absorption and scattering of light. Essentially, it's a phenomenon where electrons in a material respond to light waves in a particular way due to their natural vibrations. Full definition
