Abstract

Lead halide perovskites (LHPs) are a fascinating class of photonic materials with the potential to revolutionize various optoelectronic applications. Their diverse crystal structures, ranging from 0D to 3D configurations, offer a unique combination of properties, including high tunability and ease of synthesis. However, their inherent instability and the difficulty of patterning them into sophisticated photonic structures using conventional methods present a significant hurdle to their widespread applications. This thesis addresses these challenges by proposing a novel synthesis method that combines soft lithography and self-assembly. By utilizing a patterned template with controlled wettability, precise manipulation of LHP crystal formation is achieved, enabling the fabrication of patterned LHP structures with high crystalline quality. This innovative approach offers a scalable and practical pathway for incorporating LHPs into advanced photonic devices. This thesis will comprehensively explore LHPs, characterizing their structures, investigating their potential, and validating a novel patterning method. This comprehensive analysis aims to advance the understanding and utilization of LHPs, paving the way for their integration into next-generation photonic devices.
