Electron energy loss spectroscopy ( EELS) is a form of electron microscopy in which a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose energy and have their paths slightly and randomly deflected.
The EELS Data Base is a compilation of valence and core-loss spectra from Electron Energy Loss Spectroscopy experiments and X-Ray spectra. With 290 spectra covering 43 elements of the periodic table, it is the largest open access EELS database.
Learn what EELS is, how it works, and what information it can provide about samples. EELS uses the energy distribution of electrons that pass through a thin sample to create images and spectra with unique contrast effects.
Comúnmente llamada EELS por sus siglas en inglés (Electron Energy-Loss Spectroscopy), la espectroscopia electrónica de pérdidas de energía es una técnica de caracterización de materiales que estudia el movimiento vibracional de átomos y moléculas en y cerca de la superficie, mediante el análisis del espectro de energía de ...
Spectra per page. Showing spectra 1 to 50 out of 290. Inner & Outer Shell Excitation Spectrum Repository.
Core to all EELS experiments is spectroscopy. Here, individual or groups of spectra are recorded to extract detailed specimen information, including: composition, chemical state and collective excitations supported by the material.
4 de abr. de 2018 · Monochromated electron energy loss spectroscopy (EELS) is one of the leading techniques to study materials properties that correspond to low (<5 eV) energy losses ( i.e. band-gaps,...
