Local electrical properties and charging/discharging of CdSe/CdS core-shell nanoplatelets
2020, Applied Surface ScienceCitation Excerpt :This property is very interesting from practical point of view and such dynamic control significantly extends the scope of NCS’ applicability. In this context, the most suitable control methods are the electrical ones, such as direct charge injection [12–14], doping [15,16], electric-field control [17–19], or incorporation into LED devices [1,5–7]. Electrical properties of semiconductor NCs are commonly investigated at macro-scale, on large ensembles of nanostructures [20,21].
Recent advances in quantum dot-based light-emitting devices: Challenges and possible solutions
2019, Materials TodayCitation Excerpt :Though so-called reduced self-quenching is related to an increase in inter-dot spacing, the underlying mechanism of the FRET contribution to reduced quantum efficiency is still in doubt [139]. Typically, LEDs undergo a steady decrease in EQE with an increase in the current density, which is referred to as efficiency roll-off or efficiency droop [140,141], which has been observed in many types of QLEDs [142–145]. Individual case studies of efficiency roll-off can be conducted to measure EQEs in relation to different current densities.

2018, Chemical PhysicsCitation Excerpt :The investigation of the optical properties, particularly, absorption and photoluminescence (PL) spectrum of the semiconductor nanostructures is a topical issue, because many characteristic parameters of nanostructures are defined by them [26,27]. The investigation of the PL spectra dependence on the frequency of the incident light as well as the peak position and the shape of the PL curves depending on the main geometrical parameters of QD and different external influences have been made in the literature [28–30]. For instance, PL intensity of single CdSe QD under influence of the electric field is studied in [28].
