In this study, we have developed Ion Luminescence Microscopic Imaging and spectroscopy (ILUMIS) analysis system to establish high-resolution Ion Luminescence (IL) spectroscopy of microscopic targets. Chemical and elemental compositions of micrometer-sized particulate targets were simultaneously obtained by combining ILUMIS analysis system with conventional in-air micro-PIXE analysis system. ILUMIS system was then applied to the chemical composition analysis of individual aerosol targets obtained from the atmosphere. Organic and inorganic surface contaminants of aerosol particles were successfully obtained by IL spectroscopy and imaging. Chemical composition analysis of individual aerosol targets was satisfactorily accomplished with newly developed ILUMIS system using external proton microbeam probe.

在本研究中，我们开发了离子发光显微成像和光谱（ILUMIS）分析系统，以建立微观目标的高分辨率离子发光（IL）光谱。通过将ILUMIS分析系统与传统的空气中微型PIXE分析系统相结合，可以同时获得微米级颗粒目标的化学和元素组成。然后将 ILUMIS 系统应用于从大气中获得的单个气溶胶目标的化学成分分析。通过IL光谱和成像成功获得了气溶胶颗粒的有机和无机表面污染物。新开发的 ILUMIS 系统使用外部质子微束探头，令人满意地完成了单个气溶胶目标的化学成分分析。
