Oleksander demonstrates the power of our high throughput transient PL setup

Olkesander investigated brightly luminescent, composition- and size-selected aqueous Ag−In−S (AIS) and core/shell AIS/ZnS (ZAIS) quantum dots (QDs) by high-throughput time-resolved photoluminescence (TRPL). Both QD size and QD composition effects were probed independently by using an automated high-throughput TRPL setup. Linear relationships were found between the average PL lifetimes of AIS and ZAIS QDs and their respective bandgaps (Eg). This is a strong indication that the dynamics of radiative recombination is governed by the energetics of the QD excited state irrespective of which factor is affecting the QD bandgap, i.e., their size or composition
