Strategies for the Controlled Electronic Doping of Colloidal Quantum Dot Solids

Over the last several years tremendous progress has been made in incorporating colloidal quantum dot (CQD) solids as photoactive components in optoelectronic devices. A large part of this progress is associated with significant advancements made in controlling the electronic doping of CQD solids. Today, a variety of strategies exists towards that purpose; this Minireview aims to survey the major published works in this subject. Additional attention is given to the many challenges associated with the task of doping CQDs, as well as to the realization of optoelectronic functionalities and applications upon successful light and heavy electronic doping of CQD solids.
