制备了由几个纳米宽的间隙隔开的纳米块组成的金纳米结构，发现由于局域光学近场的增强，金纳米结构显示出很强的光致发光。所制作的结构展示了一种能够有效地发光的纳米结构金属材料，其效率可以通过调整纳米间隙宽度来调节。
Gold nanostructures consisting of nanoblocks separated by a few nanometer-wide gaps were fabricated, and found to exhibit strong photoluminescence due to enhancement of the optical near-field localized in the nanogaps. The fabricated structures demonstrate a nanostructured metallic material capable of efficient photoluminescence, whose efficiency can be adjusted by tailoring the nanogap width.
