Electron energy loss spectroscopy (EELS) is an analytical technique that can provide the structural, physical and chemical information of materials. The EELS spectra can be obtained by combining with TEM at sub-nanometer spatial resolution. However, EELS spectral information can't be obtained easily because in order to interpret EELS spectra, we need to refer to and/or compare many reference data with each other. And in addition to that, we should consider the different experimental variables used to produce each data. Therefore, reliable and easily interpretable EELS standard reference data are needed.Our Electron Energy Loss Data Center (EELDC) has been designated as National Standard Electron Energy Loss Data Center No. 34 to develop EELS standard reference (SR) data and to play a role in dissemination and diffusion of the SR data to users. EELDC has developed and collected EEL SR data for the materials required by major industries and has a total of 82 EEL SR data. Also, we have created an online platform that provides a one-stop-place to help users interpret quickly EELS spectra and get various spectral information. In this paper, we introduce EEL SR data, the homepage of EELDC and how to use them.
电子能量损失谱（EELS）是一种分析技术，能够提供材料的结构、物理和化学信息。通过与透射电子显微镜（TEM）结合，可在亚纳米空间分辨率下获得EELS谱。然而，EELS谱信息不易获取，因为为了解释EELS谱，我们需要相互参考和/或比较许多参考数据。除此之外，我们还应考虑用于生成每个数据的不同实验变量。因此，需要可靠且易于解释的EELS标准参考数据。我们的电子能量损失数据中心（EELDC）已被指定为国家标准电子能量损失数据中心34号，以开发EELS标准参考（SR）数据，并在向用户传播和扩散SR数据方面发挥作用。EELDC已为主要行业所需材料开发并收集了EEL SR数据，共有82个EEL SR数据。此外，我们创建了一个在线平台，为用户提供一站式服务，帮助他们快速解释EELS谱并获取各种光谱信息。在本文中，我们介绍了EEL SR数据、EELDC的主页以及如何使用这些数据。
