摘要: | 隨著可穿戴式元件的盛行,開發彈性可撓、可拉伸、可自修復日常使用設備的需求急劇擴大,可穿戴技術的發展儼然成為近年研究焦點。與此同時,日益迫切的環境問題也推動了發展可回收設備的需求。而在光電元件的研究領域中,以雙曲線色散著稱的超穎雙曲材料已被證明能夠強烈地促進光與物質的交互作用。然而,超穎雙曲材料的功能往往受限於其龐大的結構,阻礙了其應用前景。於本文,我們運用奈米球殼狀雙曲超穎奈米粒子結構製造出奈米粒子尺度的雙曲超穎材料元件,該元件具有包括可撓、可拉伸、可自修復及可回收的特性。其中,球殼狀雙曲超穎奈米粒子結構能夠強烈增強光與物質的交互作用,並可作為隨機雷射系統中優異的散射介質,並且,這樣的概念已通過本文中的模擬及實驗數據得到證明。本文研究中展示的雙曲超穎材料元件亦透過實驗驗證出其可撓、可拉伸及自修復的特性。此外,我們還根據元件性質展示出一種可行的回收方式。我們相信在本文展示出的奈米粒子尺度雙曲超穎材料元件能彌補傳統雙曲超穎材料元件的缺陷,並揭示奈米球殼狀雙曲超穎奈米粒子結構在各光電元件領域例如:可穿戴元件、物聯網健康檢測器級光通訊領域的巨大前景。 Of late, tremendous research has been devoted to wearable technology to meet the next generation smart living life. Dramatically expanding demands for developing flexible, robust, self-recoverable and stretchable devices for daily usage have drawn much attention to the related researchers. At the same time, the growing importance of environmental issues urges the requirement of developing recyclable devices. Among research domain of optoelectronic devices, metamaterials with hyperbolic dispersion known as hyperbolic meta-materials (HMMs) have been proven enabling to strongly boost the light-matter interaction. However, the functionality of HMM is often limited by its gigantic structure and hinder the prospects for its applicability. Here, we design, fabricate and demonstrate the first fully nano-particle-based HMM device with multi-functionalities, including self-healing, stretchable and recyclable characteristics. The core-shell hyperbolic meta-nanoparticle (HMNP) structure is able to strongly enhance the light-matter interaction and serve as superior scattering media in a random lasing system. Our proof-of- concept has been demonstrated by simulations and experimental data where a large enhancement of random lasing performance can be observed while choosing the core-shell HMNPs as scatters rather than the reference gold nanoparticles. Interestingly, our designed core-shell HMNPs device enables to remain its functionality under the harsh situations of stretching and damaging. Additionally, a feasible recycling process has also been demonstrated. We then anticipate that our study shown here reveals great prospects for the development of core-shell HMNP devices in a variety of optoelectronic applications, such as wearable widget, IOT health detector, and optical communication by providing new ways of designing. |
