요약This dissertation focuses on metal halide perovskite lasers, which have garnered significant attention for their exceptional optoelectronic properties. The research presented in this dissertation adopts a chronological and in-depth approach to delve into various aspects of perovskite lasers.The dissertation commences with an introduction to perovskites, followed by a brief review of perovskite lasers. Subsequently, it provides a comprehensive overview of perovskite material properties and carrier dynamics, fundamental to the understanding of perovskite applications. The synthesis of perovskite materials and the development of light-emitting devices are also explored.Moving forward, the dissertation delves into research on perovskite lasers, emphasizing the design, fabrication, and optimization of 1st-order distributed feedback (DFB) lasers using specific perovskite compositions. The results showcase low lasing thresholds, while also discussing techniques to further reduce thresholds and enhance device stability. These methods involve improved cavity design, material engineering, and thin film morphology engineering, collectively contributing to threshold reduction and overall performance enhancement. The research sheds light on the working dynamics of perovskite lasers and explores strategies to elevate their capabilities.The dissertation also explores perovskite patterning techniques that integrate perovskites with nano-fabrication methods. Patterning techniques are crucial in sculpting MHPs into the desired on-chip components, enabling their seamless integration and unlocking their full potential in optoelectronics. These techniques enable the creation of complex perovskite photonic devices, including color converters, micro-LEDs, patterned LEDs, and potentially electrically pumped lasers.Finally, the conclusion offers a comprehensive exploration of perovskite light-emitting applications, with a particular focus on lasers. The research presented in this dissertation significantly contributes to the understanding and advancement of perovskite-based optoelectronic devices, paving the way for their future applications in display and laser technologies.
