Colloidal quantum dots provide a powerful materials platform to engineer optoelectronics devices, opening up new opportunities in the thermal infrared spectral regions where no other solution-processed material options exist. This mini-review collates recent research reports that push the technological envelope of colloidal quantum dot-based photodetectors toward mid- and long-wavelength infrared. We survey the synthesis and characterization of various thermal infrared colloidal quantum dots reported to date, discuss the basic theory of device operation, review the fabrication and measurement of photodetectors, and conclude with the future prospect of this emerging technology.
胶体量子点为光电器件工程提供了一个强大的材料平台，在没有其他溶液处理材料选择的热红外光谱区域开辟了新的机遇。本综述整理了最近的研究报告，这些报告将基于胶体量子点的光电探测器的技术边界推向中长波红外。我们调查了迄今为止报道的各种热红外胶体量子点的合成与表征，讨论了器件运行的基本理论，回顾了光电探测器的制造与测量，并以这项新兴技术的未来前景作为总结。
