Abstract

We applied hard x-ray photoelectron spectroscopy (HAXPES) to a sample under ambient pressure conditions using an environmental cell with an approximately 24 nm-thick SiN<inf>x</inf> membrane window. As a model chemical substance, europium (II) iodide (EuI<inf>2</inf>) sealed in the cell with argon gas was investigated with HAXPES to identify the chemical species present inside the cell. The optical and morphological properties of the sample within the cell were measured with optical and fluorescent microscopy, scanning electron microscopy, cathodoluminescence, and energy dispersive x-ray spectrometry. We confirmed the effectiveness of the gas barrier properties of the cell with the SiN<inf>x</inf> window and demonstrated its applicability to various other optical and electron measurements as well as HAXPES.
