Abstract

Organic color-centers are molecularly tunable quantum defects that can be synthetically introduced into semiconducting carbon nanotube hosts. Charge carriers in the form of electron-hole pairs (or excitons) are efficiently harvested at these atomic defect sites to emit as bright shortwave-infrared photons that carry local chemical information. These intriguing properties open new possibilities of pushing the limits of sensing and imaging. In this talk, we will discuss recent advances as well as the challenges and opportunities at this emerging frontier.
