论文摘要
利用光学检测方案的诊断设备的微型化需要设计灯泡，结合了小尺寸，高性能以有效激发发色团，以及机械灵活性，以便于易于耦合具有复杂和非平面形状的组件。在这里，引入了ZnO纳米线纤维杂种，并引入了内部建筑秩序，结合了极化刺激的发射，低光模式的低传播损失以及结构灵活性。电纺材料上的超快瞬态吸收实验显示出光学增益，这会引起放大的自发发射，阈值低于膜中的值。这些系统非常灵活，可以方便地符合弯曲的表面，这使它们对各种设备平台（例如可弯曲的激光器，光学网络和传感器）以及在生物成像，照片连接链接和Optogenotogotics中的应用。
The miniaturization of diagnostic devices that exploit optical detection schemes requires the design of light-sources combining small size, high performance for effective excitation of chromophores, and mechanical flexibility for easy coupling to components with complex and non-planar shapes. Here, ZnO nanowire-in-fiber hybrids with internal architectural order are introduced, exhibiting a combination of polarized stimulated emission, low propagation losses of light modes, and structural flexibility. Ultrafast transient absorption experiments on the electrospun material show optical gain which gives rise to amplified spontaneous emission, with threshold lower than the value found in films. These systems are highly flexible and can conveniently conform to curved surfaces, which makes them appealing active elements for various device platforms, such as bendable lasers, optical networks and sensors, as well as for application in bioimaging, photo-crosslinking, and optogenetics.
