Abstract
Colloidal quantum dots, which have demonstrated its usage in optoelectronics in the visible range, are promising as infrared active materials as well. The wavelength-tunability by many variables including the nanocrystal size allows easy access to the target wavelength. Mostly, the bandgap transition is used for energy conversion. Self-doped quantum dots are the nanocrystal in which other electronic transitions are available under steady-state and ambient conditions. This talk will focus on the synthesis of the self-doped Ag2Se, HgSe QDs and their various properties including carrier dynamics studied by mid-IR spectroscopy. Additionally, several applications based on the intraband transition will be discussed.
