采用掺杂CdSe/ZnS量子点的溶剂化聚苯乙烯纳米纤维（QD/PS NFs）制备了高质量的量子点/聚苯乙烯纳米纤维。绘制的QD/PS NFs为传感应用提供超长期光稳定性，灵活性和出色的光学性能。基于这些有源NFs，成功地展示了极低功耗、快速响应和长期稳定的光学湿度传感器，这可能会导致纳米级光学传感器的新类别。
High-quality quantum-dot/polystyrene nanofibers (QD/PS NFs) are synthesized by drawing solvated PS doped with CdSe/ZnS QDs. As-drawn QD/PS NFs offer ultra-long-term photostability, flexibility, and excellent optical properties for sensing applications. Based on these active NFs, optical humidity sensors with extremely low power consumption, fast response, and long-term stability are successfully demonstrated, which may lead to a new category of nanometer-scale optical sensors.
