BPN988: Modulation of Optoelectronics in Quantum Dot Film

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...

BPN983: Materials and Devices for Bright UV LEDs

Shu Wang
2023

Wide band gap semiconductors are crucial for applications in power electronics, displays, solid-state lightning and many other fields. Due to their intrinsic structure and electronic properties, many wide band gap semiconductors can not be intentionally doped as desired, which limits their role in electronic and optoelectronic devices. In this project, we propose tuning the optoelectronic properties of wide band gap semiconductors electrically to enhance its luminescence efficiency.

2023

We demonstrate an alternating current (AC) driven light emitting capacitor in which the color of the emission spectra can be changed via an applied AC frequency. The device has a simple metal-oxide-semiconductor (MOS) capacitor structure with an organic emissive layer, enabling facile fabrication processing. The organic emissive layer comprises a thin, submonolayer low energy dye layer underneath a thick host matrix (∼30 nm) with higher energy emitting dyes. The emission of the lower energy dyes dominates at low frequency, while the higher energy emission of the host matrix dominates at...
