| 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. Astronomical Imaging Astronomical imaging can be broadly divided into two categories: (1) steady-state imaging, in which long exposures are required to capture ultra-low-light-level objects, and (2) time-resolved photometry, in which integration times range from milliseconds to a few seconds. General Raman The most common application of Raman spectroscopy involves the vibrational energy levels of a molecule. Incident laser light in the UV, visible or NIR, is scattered from molecular vibrational modes. Surface-Enhanced Raman Spectroscopy SERS - Surface-enhanced Raman spectroscopy Bose-Einstein Condensate Bose-Einstein condensate (BEC) can be regarded as matter made from matter waves. It is formed when a gas composed of a certain kind of particles, referred to as “bosonic” particles, is cooled very close to absolute zero. 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. 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. Micro-Computed Tomography Micro Computer Tomography is a unique technique for the noninvasive, nondestructive 3D characterization of materials down to a micrometer scale. |
