We demonstrate and verify the in-situ addition of a collecting lens for electroluminescence experiments to an existing scanning tunneling microscope. We fabricate a simple clip-on lens that we reversibly attach at the sample plate via regular sample transfer tools to collimate the light emitted from a plasmonic tunneling junction to the viewport ordinarily used for optical access. The proximity of the lens to the tunneling junction allows us achieve good collection efficiencies, demonstrating the quick turnaround of converting an existing setup with optical access into a practical scanning luminescence microscope. We verify the function of the clip-on lens by measuring the bias dependent plasmon of Au, Ag, and spatial luminescence maps.•Reversible clip-on lens.•In-situ transfer.•Luminescence.
我们展示并验证了在现有扫描隧道显微镜上原位添加用于电致发光实验的收集透镜。我们制作了一个简单的夹式透镜，通过常规的样品转移工具将其可逆地连接在样品板上，以将等离子体隧穿结发出的光准直到通常用于光学观察的视口。透镜与隧穿结的接近度使我们能够实现良好的收集效率，展示了将具有光学观察功能的现有装置快速转变为实用的扫描发光显微镜的过程。我们通过测量金、银的偏压相关等离子体以及空间发光图谱来验证夹式透镜的功能。
