论文摘要
我们展示了一种乳液聚合技术，可用于嵌入二苯乙烯掺杂的蒽纳米晶（PMMA）纳米胶囊中。纳米胶囊在制造后不需要进一步的保护，并且与未受保护的蒽相比具有抗升华性。单二苯甲酸分子分子的室温发射稳定，在冷却到低温温度时，与现有的生长方法相比，它们出色的光学特性没有变化。现在，这些强大的纳米胶囊具有表面功能化和集成到纳米光子设备中的潜力，在该设备中，所使用的材料与基于聚合物的设计兼容。
We demonstrate an emulsion-polymerisation technique to embed dibenzoterrylene-doped anthracene nanocrystals in polymethyl methacrylate (PMMA) nanocapsules. The nanocapsules require no further protection after fabrication and are resistant to sublimation compared to unprotected anthracene. The room temperature emission from single dibenzoterrylene molecules is stable and when cooled to cryogenic temperatures we see no change in their excellent optical properties compared to existing growth methods. These now robust nanocapsules have potential for surface functionalisation and integration into nanophotonic devices, where the materials used are compatible with incorporation in polymer-based designs.
