Abstract

We present a method that uses viscosity-lowering materials to fabricate flexible polydimethylsiloxane-based quantum dot (QD) films with high quantum yield (QY) and improved uniformity. We found that the aggregation of individual QDs was prevented, and the QY improved simultaneously in films that contained surfactants. These films showed an improved absorption of approximately 27% in the near-UV and blue light regions, along with an improved photoluminescence of approximately 18%, indicating improved light conversion from the UV to the visible frequency region.

制造具有高量子产率的均匀量子点薄膜。

我们介绍了一种使用降粘材料制造基于聚二甲基硅氧烷的柔性量子点薄膜的方法，这种薄膜具有高量子产率和更好的均匀性。我们发现，在含有表面活性剂的薄膜中，单个量子点的聚集得到了防止，量子产率也同时得到了提高。这些薄膜在近紫外线和蓝光区域的吸收率提高了约 27%，光致发光率提高了约 18%，表明从紫外线到可见光频率区域的光转换得到了改善。

期刊介绍： The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
