Combined Raman and Photoluminescence Imaging of 2D WS<sub>2</sub>
26 Dec 2017Raman and photoluminescence spectroscopy and imaging are used to examine the spatial variation of solid state structure and electronic character of two dimensional (2D) WS2 crystals. Simultaneous acquisition of photoluminescence spectra with the Raman scattering provides complementary ways of rendering Raman and photoluminescence spectral images of thin film WS2.

Raman SpectroscopyRaman spectroscopy is used to discern the vibrational and rotational states of molecules and hence the chemical composition of a sample by measuring the inelastic scattering of monochromatic light. Explore a range of Raman spectrometers, including handheld/portable Raman spectrometers for QC/QA labs and in situ spectrometers for processes. Conduct Raman imaging for microanalysis of mixed samples using a Raman microscope. Raman spectrographs are also available.
