| Tip-Enhanced Raman Spectroscopy TERS - Tip-Enhanced Raman spectroscopy Fluorescence, Phosphorescence, and Photoluminescence Spectroscopy Fluorescence, phosphorescence and photoluminescence occur when a sample is excited by absorbing photons and then emits them with a decay time that is characteristic of the sample environment. Surface-Enhanced Raman Spectroscopy SERS - Surface-enhanced Raman spectroscopy Coherent Anti-Stokes Raman Spectroscopy Coherent Anti-Stokes Raman spectroscopy (CARS) a type of non-linear Raman spectroscopy. Instead of the traditional single laser, two very strong collinear lasers irradiate a sample. Resonance Raman Spectroscopy Instead of fluorescence, some types of colored molecules produce strong Raman scattering at certain conditions. This effect was called Resonance Raman. Stimulated Raman Scattering Stimulated Raman scattering takes place when an excess of Stokes photons that were previously generated by normal Raman scattering are present or are deliberately added to the excitation beam. |
