我们研制了一种采用脉冲无声放电激发的二元混合稀有气体的真空紫外闪光灯。在Kr/Ar无声放电中，VUV发射光谱宽度在162 nm的中心波长处扩展到26 nm半高全宽（FWHM）。根据动力学分析，混合稀有气体中的这种光谱扩展归因于来自异质稀有气体准分子（Kr 2 *）和同质稀有气体准分子（Kr 2 * 和Xe 2 *）的同时发射。
We have developed a vacuum ultraviolet (VUV) flash lamp using a binary rare gas mixture excited by a pulsed silent discharge. In a Kr/Xe silent discharge, the VUV emission spectral width was extended up to 26 nm full width at half‐maximum (FWHM) at a center wavelength of 162 nm. According to kinetic analyses, such a spectral extension in mixed rare gases is attributed to the simultaneous emissions from heteronuclear rare gas excimers (KrXe*) and homonuclear rare gas excimers (Kr2* and Xe2*).
