On the use of time-resolved photoluminescence as a probe of nanocrystal photoexcitation dynamics

It is becoming increasingly evident that to exploit nanocrystals in light-harvesting applications requires a high-level understanding of the interactions that link exciton states with surface states and the surrounding environment. Recent research has established time-resolved photoluminescence as a quantitative tool for the analysis of photoexcitation dynamics in colloidal semiconductor nanocrystals. Here, we discuss the analysis of time-resolved photoluminescence data in the context of nanocrystal dynamics. We introduce the idea that dynamical processes might imprint easily identified signatures into the decays and we suggest future work in the field.
