Quantum dots (QDs), with size-tunable bandgaps and favorable interfacial properties, significantly enhance photoelectrochemical (PEC) water splitting by enabling broad-spectrum light harvesting, optimized band alignment, and improved charge separation. However, QD design strategies for PEC systems remain less developed compared to those for light-emitting diodes and solar cells, constrained by incomplete understanding of interfacial photophysics, limited exploration of low-dimensional nanocrystals (1D/2D), and the absence of AI-assisted optimization. This review provides a comprehensive overview of material design strategies for QDs in PEC hydrogen production, encompassing fundamental principles, established approaches, and recent advances in both heavy-metal-based and nontoxic systems. Particular attention is given to emerging paradigms such as dimensional control and AI-driven optimization, which enable predictive modeling, accelerated synthesis, and performance tuning beyond conventional trial-and-error methods. Finally, we address critical challenges—including stability, toxicity, and scalability—and outline future directions for achieving efficient, sustainable QD-based PEC systems suitable for practical and economically viable commercialization. 2025-12-31T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/60215 Title: Advances in Photopatterning of Quantum Dots: Mechanisms, Materials, and Device Applications Author(s): Lee, Namji; Taylor Derrick Allan; Choi, Donghyun; Kwak, Do-Hyun; Lee, Jong-Soo Abstract: The precise patterning of quantum dots (QDs) is crucial for integrating advanced optoelectronic devices, including quantum dot light-emitting diodes (QLEDs) and photodetectors. However, conventional patterning techniques often suffer from poor film uniformity and degradation of the optical and electronic properties of QDs. Recently, direct optical lithography has emerged as a powerful alternative, enabling high-resolution patterning while better preserving QD integrity. In this review, we summarize the representative photopatterning mechanisms, including ligand exchange, ligand cross-linking, ligand decomposition, and ligand desorption and discuss the associated material considerations, including QDs, surface ligands, and charge-transport layers. We further highlight recent breakthroughs in applying these strategies to QLEDs and photodetectors. Finally, we outline the remaining challenges - including solubility control, industrial scalability, photodamage mitigation, and the optimization of processing conditions - and propose potential strategies for enhancing patterning quality, device performance, and manufacturability. 2026-01-31T15:00:00Z
