A conventional EELS implementation involves the incorporation of an energy loss spectrometer onto a transmission electron microscope (TEM). The TEM utilizes accelerated electrons to image and magnify regions of an electron transparent sample. Due to their very small de Broglie wavelength (0.0025 nm for 200 keV electrons), these electrons have an extremely high resolving power

eels的元素成分分布图主要有tem-eels作图和stem-eels作图两种。 锂电池现在是最流行的可充电电池，然而电极中锂的直接观察到现在还没解决。 锂的K-吸收边很明显，可以根据这一特征能量，做出锂的元素成分分布图，如图6所示，采用TEM-EELS模式来对锂进行观察，其中(b)中浅色表示锂的存在。
Over the last three decades, electron energy loss spectroscopy (EELS) has become a formidable characterization technique. Used in combination with a transmission electron microscope (TEM), it can provide atomic-level chemical and structural characterization. This includes information about elemental composition, chemical bonding, oxidation ...
EELS spectrometry is a method of measuring the energy lost by the interaction of electrons with atoms as they pass through a thin sample. It is possible to identify the constituent elements and their electronic structures. Compared to energy dispersive X-ray (EDX) spectroscopy, EELS has the following advantages.
TEM-EELS. 1. Introduction. In terms of the research of recent advanced materials or nano-materials, microstructure analysis becomes important and it requires ultra high spatial resolution. Electron energy-loss spectroscopy in transmission electron microscopy (TEM-EELS) and energy-filtering TEM (EFTEM) are powerful tools to analyze the ...
