Aggregation-induced emission (AIE) molecules have great potential to enhance the performance of micronano lasers due to their excellent aggregated luminescence properties, so it is valuable to expand their applications in micronano lasers. In this work, a typical AIE active fluorescent dye motif 9,10-bis(2,2-diphenylvinyl) anthracene (BDPVA) was selected as the gain medium. First, drop-casting was used to fabricate BDPVA single-crystal nanowires, which can be used as Fabry–Perot (FP)-type resonators with a lasing threshold of 49.4 μJ/cm2. Furthermore, we innovatively doped BDPVA molecules as gain mediums into external polymer Whispering-Gallery-Mode (WGM)-type resonators via the emulsion self-assembly method. Fabricated BDPVA-doped polystyrene (PS) microspheres exhibit a much lower lasing threshold of 9.04 μJ/cm2. These results prove that the BDPVA molecules, in addition to realizing the reported AIE single-crystal lasers, can also be used as a guest-doped gain medium in the resonant cavity for obtaining better fluorescence gain. In addition, multimode tunability of two types of lasers has been successfully achieved by tuning the structure of the resonant cavity. This work further expands the application potential of AIE materials and will provide a useful reference for the rational design and fabrication of photonic micronano laser components using AIE materials.

基于聚集诱导发射分子的微纳米激光器：多种谐振腔研究
聚集诱导发射（AIE）分子由于其优异的聚集发光特性，在提升微纳激光器性能方面具有巨大潜力，因此拓展其在微纳激光器中的应用具有重要价值。在这项工作中，选择典型的 AIE 活性荧光染料基序 9,10-双（2,2-二苯基乙烯基）蒽（BDPVA）作为增益介质。首先，采用滴铸法制备了BDPVA单晶纳米线，该纳米线可用作法布里-珀罗（FP）型谐振器，激光阈值为49.4 μJ/cm 2 。此外，我们创新性地通过乳液自组装方法将 BDPVA 分子作为增益介质掺杂到外部聚合物耳语画廊模式 (WGM) 型谐振器中。制造的 BDPVA 掺杂聚苯乙烯 (PS) 微球表现出低得多的激光阈值，为 9.04 μJ/cm 2 。这些结果证明BDPVA分子除了可以实现所报道的AIE单晶激光器外，还可以用作谐振腔中的客体掺杂增益介质，以获得更好的荧光增益。此外，通过调谐谐振腔的结构，成功实现了两种激光器的多模可调。该工作进一步拓展了AIE材料的应用潜力，将为利用AIE材料合理设计和制造光子微纳激光元件提供有益的参考。
