Yttrium is a metal whose optical properties are tunable by hydrogen incorporation. Commonly, this happens via exposure to hydrogen gas. Here, we demonstrate that the hydrogenation of yttrium is also possible via the deprotonation of alcoholic liquids. Palladium-covered yttrium is placed in an ethanol bath that causes the deprotonation of ethanol and the hydrogenation of yttrium to yttrium dihydride. Proof-of-concept is presented with a study on thin films, which is followed by tuning the optical properties of plasmonic nanoantennas. The liquid hydrogenation causes the plasmonic resonance to shift by more than 300 nm in the near-infrared spectral range. Consequently, we show that our plasmonic nanoantennas serve as a local nanooptical indicator for the deprotonation process. Our findings pave to road toward a (nano)optical investigation and detection of catalytic processes in liquids without the need of electrical, chemical, or electrochemical read-out.

通过醇去质子化等离子体纳米天线的液体氢化
钇是一种金属,其光学特性可通过掺入氢进行调节。通常,这是通过暴露于氢气而发生的。在这里,我们证明了钇的氢化也可以通过酒精液体的去质子化。钯覆盖的钇被置于乙醇浴中,导致乙醇去质子化和钇氢化成二氢化钇。对薄膜的研究提出了概念验证,然后调整等离子体纳米天线的光学特性。液体氢化导致等离子体共振在近红外光谱范围内移动超过 300 nm。因此,我们表明我们的等离子体纳米天线可作为去质子化过程的局部纳米光学指示器。
