Black phosphorus has emerged as a unique optoelectronic material, exhibiting tunable and high device performance from mid-infrared to visible wavelengths. Understanding the photophysics of this system is of interest to further advance device technologies based on it. Here we report the thickness dependence of the photoluminescence quantum yield at room temperature in black phosphorus while measuring the various radiative and non-radiative recombination rates. As the thickness decreases from bulk to ~4 nm, a drop in the photoluminescence quantum yield is initially observed due to enhanced...

BPN988: Modulation of Optoelectronics in Quantum Dot Film

I K M Reaz Rahman
Naoki Higashitarumizu
2023

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...
