Efficient Tandem Quantum-Dot LEDs Enabled by An Inorganic Semiconductor-Metal-Dielectric Interconnecting Layer Stack

Qianqian Wu et al.

Summary: A newly developed interconnecting layer in tandem QLEDs has lead to record efficiencies in light emission, preventing charge imbalance and solvent damage and achieving high levels of external quantum efficiency. This interconnecting layer covers emission wavelengths from blue to red light, allowing for high performance light emission.

Light-emitting field-effect transistors with EQE over 20% enabled by a dielectric-quantum dots-dielectric sandwich structure

Lingmei Kong et al.

Summary: This study reports highly efficient QLEFETs with an external quantum efficiency (EQE) of over 20% by employing a dielectric-QDs-dielectric (DQD) sandwich structure. The DQD structure controls carrier behavior and shifts the exciton recombination zone into the emissive layer, resulting in enhanced radiative recombination and preventing exciton loss and luminescence quenching.

Suppressing the Cation Exchange at the Core/Shell Interface of InP Quantum Dots by a Selenium Shielding Layer Enables Efficient Green Light-Emitting Diodes

Zhongjiang Sun et al.

Summary: Indium phosphide (InP) quantum dots (QDs) with highly luminescent InP/ZnSe/ZnS QDs were successfully synthesized by constructing Se-rich shielding layers on the surfaces of InP cores, which improved the external quantum efficiency of QLED devices at high luminance.

Extremely Slow Trap-Mediated Hole Relaxation in Room-Temperature InP/ZnSe/ZnS Quantum Dots

Anh T. Nguyen et al.

Summary: Time-resolved photoluminescence and transient absorption spectroscopy were used to study hole relaxation dynamics in high-quality InP/ZnSe/ZnS quantum dots. Hole relaxation rates varied with In/P ratio, emission wavelength, and excess indium content. Slow hole relaxation in red-emitting QDs was attributed to transient population of indium-based traps in the ZnSe shell.

Negative Trion Auger Recombination in Highly Luminescent InP/ZnSe/ZnS Quantum Dots

Taehee Kim et al.

Summary: The study reveals that the Auger recombination processes of InP/ZnSe/ZnS quantum dots are influenced by the midshell structures, ultimately affecting the performance of QD-LEDs. The midshell thickness impacts the exciton-exciton binding energy and the negative trion Auger recombination behavior.

Enhancement Mechanism of Quantum Yield in Alloyed-Core/Shell Structure of ZnS-CuInS2/ZnS Quantum Dots

Hyeong Seop Shim et al.

Summary: CuInS2 (CIS) quantum dots (QDs) show potential as attractive alternatives to toxic QDs when their quantum yield (QY) becomes comparable. The enhancement of QY in alloyed core/shell structures is attributed to the evolution of electronic structures and suppression of defect states, leading to broad spectral bands and reduced toxicity concerns.
