Semiconductors nanocrystals (NCs) exhibiting localized surface plasmon resonances (LSPRs) have recently emerged as useful tools in biomedical applications (photothermal therapy, enhanced drug delivery, imaging diagnostics, etc.), water splitting and carbon dioxide reduction catalysis, chemo- and biosensors, energy generation, conversion, and storage. In contrary to the conventional LSPR materials (noble metals), the semiconductors LSPR NCs allow a wide range of wavelength tunability of LSPRs from visible towards the near-infrared region (NIR) and further to mid-IR. That led to the adoption of those NCs in various applications wherein the effective tuning of IR characteristics is relevant for biological therapeutic window and tissue attenuation curves, solar spectrum, telecom window, waste heat spectral region, etc. The presented paper briefly reviews the library of semiconductor LSPR NCs, describes the mechanisms of LSPR tuning within NIR and mid-IR, and focuses on the state-of-the-art achievements in implementing LSPR NCs in various energy subjects such as solar energy harvesting via photovoltaics and steam generation, devices for effective energy use and storage, water splitting i.e. hydrogen evolution, elucidates the nature of above processes. To date, to the best of our knowledge within reviews on the fabrication, properties, and applications of LSPR semiconductor NCs, their applicability in energy conversion, storage, and related topics has not yet been summarized.

表现出局部表面等离振子共振（LSPR）的半导体纳米晶体（NCs）最近已成为生物医学应用（光热疗法，增强的药物递送，成像诊断等）中的有用工具。），水分解和二氧化碳还原催化，化学和生物传感器，能量产生，转换和存储。与传统的LSPR材料（贵金属）相反，半导体LSPR NC允许LSPR从可见光到近红外区域（NIR），再到中红外的波长可调范围很广。这导致了这些NC在各种应用中的采用，其中IR特性的有效调整与生物治疗窗和组织衰减曲线，太阳光谱，电信窗，废热光谱区域等有关。。本文简要回顾了半导体LSPR NC的库，描述了NIR和中红外中LSPR调整的机制，并重点介绍了在各种能量主题（例如太阳能收集）中实施LSPR NC的最新成果。通过光伏发电和蒸汽产生，用于有效利用和存储能量的装置，水分解即放出氢气，阐明了上述过程的性质。迄今为止，据我们所知，在对LSPR半导体NC的制造，性能和应用进行评论时，尚未总结它们在能量转换，存储和相关主题中的适用性。
