■ Abstract : Colloidal quantum dots are compelling semiconductor materials for optoelectronic applications owing to their tunable bandgap, solution-processibility, and ambient stability. Of chief importance is the ability to tune their absorption and emission into the infrared, a region of interest in optical communications, night vision, biological imaging, and infrared photovoltaics. However, there remain many challenges to be addressed for practical applications in optoelectronics, mostly on device performance and stability. In this talk, I will briefly overview recent efforts to address these issues and introduce various strategies to make efficient colloidal quantum dot optoelectronics for infrared applications.
