论文摘要

我们将通过反应性磁控溅射到化学成分合成的稀土氧 - 水薄膜(Yho,Ndho,Gdho和Dyho)的光致变色反应。样品组成的深度谱通过多方法离子束分析方法提取。薄膜的总面积密度是从卢瑟福的反向散射光谱中推导的,而巧合的飞行时间/能量弹性后弹性检测分析则提供了膜成分的深度profiles。从核反应分析和弹性反向散射光谱法中提取了光种的浓度,即氢和氧的高分辨率深度谱。薄膜的光致变色反应通过光照射前后的光学传输光谱进行测量。我们向YHO,NDHO,GDHO和DYHO的光子特性报道了由公式$ reh_ {2-δ}O_Δ$描述的化学成分,范围为$ 0.45 {<}δ{<}δ{<} 1.5 $。

We relate the photochromic response of rare-earth oxy-hydride thin films (YHO, NdHO, GdHO and DyHO) synthesized by reactive magnetron sputtering to chemical composition. Depth profiles of the sample composition are extracted by a multi-method ion beam analysis approach. The total areal density of the thin films is deduced from Rutherford Backscattering Spectrometry while coincidence Time-of-Flight/Energy Elastic Recoil Detection Analysis provides depth-profiles of the film constituents. High-resolution depth profiles of the concentration of light species, i.e. hydrogen and oxygen, are additionally extracted from Nuclear Reaction Analysis and Elastic Backscattering Spectrometry, respectively. The photochromic response of the films is measured by optical transmission spectroscopy before and after illumination. We report photochromic properties for YHO, NdHO, GdHO and DyHO for chemical compositions described by the formula $REH_{2-δ}O_δ$ in the range of $0.45 {<} δ {<} 1.5$.
