Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.

A research team led by Prof. Fang Yonghua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences proposed and systematically optimized a novel parabolic mirror ...

At its simplest, Raman spectroscopy is a light-scattering technique. When monochromatic light, usually from a laser, hits a sample, most of it returns unchanged. But a small portion scatters ...

Semiconductor nanocrystals are conducting materials with a size that has been reduced to the nanoscale. This size reduction can greatly enhance the physical, chemical, and optical characteristics, ...

(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...

Graphene is a material that has a one-atom layer of carbon atoms with a thickness of only 335 pm. It can be modified using oxidization and functionalization. For example, graphene gains properties ...

Visualization of Tip-Enhanced Raman Spectroscopy (TERS): This diagram illustrates the interaction of a laser beam with a sample surface through a sharp metallic tip. The red laser light excites the ...
