A photonic crystal is a periodic structure for manipulating light propagation and optical applications, which is analogous to semiconductor crystals such as silicon for electronics. A perovskite is a semiconductor material with potential applications in solar cells and other devices. In this project, PIs will combine perovskites with photonic crystals for light generation and absorption. The perovskites will be confined inside tiny tubular material in order to improve their stability when they are under harsh environment such as intense light, moisture, and oxygen. The photonic crystal will be made in a way that light will be localized and amplified even if the photonic crystal has a fabrication imperfection. If successful, the project will lead to high-efficiency integrated lasers and solar cell devices. This project will enhance the abilities in the education arena by enriching program offerings for graduates and undergraduates, including minority and underrepresented students, adding new capabilities in scientific research, expanding the range of laboratory exercises available to students, and training them as competitive next-generation workforce in nanotechnology, clean-energy, photonics technology. It also includes outreach activities targeting the general public via the Fort Worth Museum of Science and History. Technical partThe objective is to design, fabricate and characterize meta-photonic devices with high absorption and topological photonic devices using encapsulated perovskites in NiO nanotubes with a topological configuration that is immune to local disorders. Three approaches will be used: PIs will study the photo-stability of perovskites/NiO nanotubes under multiple-photon exposure, and their photoluminescence and electroluminescence in light emitting devices; Bound states in the continuum in the graded photonic super-crystal will be applied to the design of the resonant cavity with a very high quality factor for the lasing of the active medium of perovskites/NiO nanotubes. Disorders or broken in-plane inversion symmetry will be incorporated into asymmetric graded photonic super-crystals to achieve quasi bound states in the continuum that will be immune to the fabrication imperfection of NiO nanotubes; High-order Mie-resonances in individual NiO nanotube and bound states in the continuum will be utilized to achieve the broadband high absorption in perovskite/NiO nanotubes patterned in asymmetric graded photonic super-crystal. The goal is to achieve high-efficiency solar cells and electrically pumped laser in perovskite/NiO nanotubes patterned in the graded photonic super-crystal. The proposed research will have a significant impact on lasing medium in stabilized perovskites, micro/nano-cavity lasers, integrated optical circuit, miniature optical devices, and photovoltaic devices.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

光子晶体是一种用于操纵光传播和光学应用的周期性结构，类似于用于电子产品的半导体晶体，如硅。钙钛矿是一种半导体材料，在太阳能电池和其他设备中具有潜在的应用前景。在这个项目中，PI将把钙钛矿和光子晶体结合起来，以产生和吸收光。钙钛矿材料将被限制在微小的管状材料中，以提高其在强光、潮湿和氧气等恶劣环境下的稳定性。该光子晶体将以这样一种方式制造，即使该光子晶体存在制造缺陷，光也将被局部化和放大。如果成功，该项目将带来高效率的集成激光器和太阳能电池设备。该项目将通过丰富研究生和本科生(包括少数族裔和代表性不足的学生)的课程提供，增加新的科学研究能力，扩大学生可进行的实验室练习范围，并将他们培养成纳米技术、清洁能源、光子技术方面具有竞争力的下一代劳动力，从而提高教育领域的能力。它还包括通过沃斯堡科学和历史博物馆面向普通公众的外联活动。技术部分的目标是设计、制造和表征具有高吸收和拓扑结构的超光子器件，该器件使用包裹在NiO纳米管中的钙钛矿，具有不受局域无序影响的拓扑结构。将使用三种方法：PIS将研究钙钛矿/NiO纳米管在多光子曝光下的光稳定性，以及它们在发光器件中的光致发光和电致发光；梯度光子超晶体中的束缚态将被应用于具有非常高品质因数的谐振腔的设计，以用于钙钛矿/NiO纳米管的有源介质的激光。在非对称梯度光子超晶体中引入无序或破缺的面内反转对称性，在非对称梯度光子超晶体中实现准束缚态，使其不受NiO纳米管制备缺陷的影响；利用单个NiO纳米管中的高阶Mie共振和连续体中的束缚态来实现非对称梯度光子超晶体中钙钛矿/NiO纳米管的宽带高吸收。其目标是在梯度光子超晶体中图案化的钙钛矿/NiO纳米管中实现高效太阳能电池和电泵浦激光。这项拟议的研究将对稳定钙钛矿、微纳腔体激光器、集成电路、微型光学器件和光伏器件中的激光介质产生重大影响。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
