Size-dependent electronic transition is the prominent feature of quantum materials. Colloidal quantum dot is the most confined nanomaterial in dimension, showing the discrete electronic states even in the conduction band. The intraband transition, occurring between the quantized states of the conduction band of colloidal quantum dot, had been studied for the last two decades mostly by using ultrafast spectroscopy due to the fast hot-carrier relaxation. Recently, the steady-state intraband transition has been successfully observed from the self-doped nanocrystals. In this presentation, the novel optical, electronic and magnetic properties of the self-doped colloidal nanocrystals will be discussed, which had been a long-standing challenge in the colloidal nanocrystal field.
