Colloidally prepared, two-dimensional semiconductor nanostructures offer advantages for numerous classes of application including energy capture and conversion, detection, and biolabeling. We perform an array of photophysical characterizations of these systems to obtain the thorough understanding of fundamental desired and undesired processes of exciton and charge transport in addition to multiexcitonic behaviors of relevance to gain and lasing. Presented studies using time-resolved optical methods such as absorption and emission as functions of sample temperature and photon energy suggest especially rapid energy transfer, charge transfer rates that offer suggestions regarding spatial exciton distribution in plane, and outstanding optical performance for laser action.
