BPN988: Modulation of Optoelectronics in Quantum Dot Film


Core/shell quantum dots are known to have high photoluminescence quantum yield for their passivation through thicker shell by suppressing surface trap states. In spite of their excellent exciton dynamics, these bright quantum dots tend to suffer from stability issues and degradation over time. Here we investigate their photo-physical properties due to charge injection, which leads to unfavorable recombination pathways through charged excitons. This provides an additional tuning knob for modulation of their photoluminescence quantum yield after synthesis, thereby offering a means of color tunability in a reversible fashion through electrostatic control.
