Infrared technologies provide tremendous value to our modern-day society. The need for easy-to-fabricate, solution-processable, tunable infrared active optoelectronic materials has driven the development of infrared colloidal quantum dots, whose band gaps can readily be tuned by dimensional constraints due to the quantum confinement effect. In this Perspective, we summarize recent progress in the development of infrared quantum dots both as infrared light emitters (e.g., in light-emitting diodes, biological imaging, etc.) as well as infrared absorbers (e.g., in photovoltaics, solar fuels, photon up-conversion, etc.), focusing on how fundamental breakthroughs in synthesis, surface chemistry, and characterization techniques are facilitating the implementation of these nanostructures into exploratory device architectures as well as in emerging applications. We discuss the ongoing challenges and opportunities associated with infrared colloidal quantum dots.

红外量子点：进展，挑战和机遇

红外技术为我们的现代社会提供了巨大的价值。对易于制造，可溶液加工，可调谐的红外有源光电材料的需求推动了红外胶体量子点的发展，由于量子限制效应，其带隙可以很容易地通过尺寸约束来调节。在此观点中，我们总结了红外量子点作为红外光发射器（例如，在发光二极管，生物成像等中）以及红外吸收剂（例如，在光伏，太阳能，光子中）的开发方面的最新进展。上转换等。），重点介绍合成，表面化学和表征技术的根本突破如何促进将这些纳米结构实现到探索性设备架构以及新兴应用中。我们讨论了与红外胶体量子点相关的持续挑战和机遇。
