In this paper, we demonstrate plasmonic substrates prepared on demand, using a straightforward technique, based on laser-induced photochemical reduction of silver compounds on a glass substrate. Importantly, the presented technique does not impose any restrictions regarding the shape and length of the metallic pattern. Plasmonic interactions have been probed using both Stokes and anti-Stokes types of emitters that served as photoluminescence probes. For both cases, we observed a pronounced increase of the photoluminescence intensity for emitters deposited on silver patterns. By studying the absorption and emission dynamics, we identified the mechanisms responsible for emission enhancement and the position of the plasmonic resonance.
在本文中，我们展示了按需制备的等离子体基片，该基片使用基于激光诱导玻璃衬底上的银化合物光化学还原的简单技术制备。重要的是，所提出的技术对于金属图案的形状和长度没有任何限制。使用作为光致发光探针的斯托克斯和反斯托克斯型发射器来探测等离子体相互作用。对于这两种情况，我们观察到发射体在银图案上的光致发光强度明显增加。通过研究吸收和发射动力学，我们确定了发射增强的机制以及等离子体共振的位置。
