基于异质结蜡升华和水溶性材料的具有瞬态功能的自然降解光子器件
Naturally-Degradable Photonic Devices with Transient Function by Heterostructured Waxy-Sublimating and Water-Soluble Materials
摘要：
介绍了一种基于水溶性染料掺杂聚合物在非极性环烃升华基底上的组合式干湿瞬态材料和器件。显示放大的自发发射的发光异质结构被用作无散斑、全场成像的照明源，并且实现了包含具有稳定编码信息的QR码的瞬态光学标签。瞬态行为也在微观尺度上进行了研究，突出了升华化合物中的材料域的实时演化。最后，耗尽的组分完全溶于水，因此可自然降解。
英文摘要：
Combined dry-wet transient materials and devices are introduced, which are based on water-dissolvable dye-doped polymers layered onto non-polar cyclic hydrocarbon sublimating substrates. Light-emitting heterostructures showing amplified spontaneous emission are used as illumination sources for speckle-free, full-field imaging, and transient optical labels are realized that incorporate QR codes with stably encoded information. The transient behavior is also studied at the microscopic scale, highlighting the real time evolution of material domains in the sublimating compound. Finally, the exhausted components are fully soluble in water thus being naturally degradable.
