摘要

宽吸收材料,其特点是可调谐的吸收在紫外到中红外光谱区域,已经成为一类重要的光电材料。有机和无机材料取得了重大进展;然而,目前的增强策略仍然主要是平台特定的,没有统一的物理框架指导。为了解决这一差距,本文介绍了一个基于跃迁概率理论的三因素物理模型,从而为理解电子跃迁如何在轨道、振动和自旋维度上调制提供了一致的理论基础。在经典材料平台中系统地检查了结构-机制-性能关系。此外,还讨论了等离子体共振等外场增强机制对光谱展宽和局域场增强的贡献。基于清晰的机制认识和目标材料设计,重点介绍了将宽吸收材料集成到宽带光电探测器中的最新进展,强调了它们的实际意义。本文探讨了高性能宽带光电系统的三个核心挑战和机制驱动设计策略,为未来的发展提供了指导性的展望。

Broad-absorbing materials for photodetectors

Broad-absorbing materials, characterized by their tunable absorption across the ultraviolet to mid-infrared spectral regions, have emerged as a crucial class of optoelectronic materials. Significant advances have been achieved in organic and inorganic materials; however, current enhancement strategies remain largely platform-specific and are not guided by a unified physical framework. To address this gap, this review introduces a three-factor physical model grounded in the theory of transition probability, thereby providing a consistent theoretical basis for understanding how electronic transitions are modulated across orbital, vibrational, and spin dimensions. Structure-mechanism-performance relationships are systematically examined in classic material platforms. In addition, the contributions of external-field enhancement mechanisms, such as plasmonic resonance, to spectral broadening and local-field enhancement are discussed. Based on clear mechanistic insight and targeted materials design, recent advances in integrating broad-absorbing materials into broadband photodetectors are highlighted, emphasizing their practical relevance. The review examines the three core challenges and mechanism-driven design strategies for high-performance broadband optoelectronic systems, providing an instructive outlook for future advancements.
