摘要:

我们提出了一种方法来实现有源光学尖用于近场光学,可以在室温下工作。金属涂覆的光学尖端覆盖有薄的聚合物层,该聚合物层以低密度被CdSe纳米晶体或纳米棒染色。的发射率和发射光谱的活性尖端的时间分析表明,一个非常小的数量的颗粒-可能下降到只有一个-可以在尖端顶点活跃。这为使用单个无机纳米颗粒作为光源的近场光学开辟了道路。

英文摘要:

We present a method to realize active optical tips for use in near-field optics that can operate at room temperature. A metal-coated optical tip is covered with a thin polymer layer stained with CdSe nanocrystals or nanorods at low density. The time analysis of the emission rate and emission spectra of the active tips reveal that a very small number of particles - possibly down to only one - can be made active at the tip apex. This opens the way to near-field optics with a single inorganic nanoparticle as a light source.
