Ultrasmall CsPbBr3 Blue Emissive Perovskite Quantum Dots using K-alloyed Cs4PbBr6 Nanocrystals as Precursors
Clara Otero Martinez, Matteo L. Zaffalon, Yurii Ivanov +11
We report a colloidal synthesis of blue emissive, stable cube-shaped CsPbBr3 quantum dots (QDs) in the strong quantum confinement regime via a dissolution-recrystallization startin…
Extending the Defect Tolerance of Halide Perovskite Nanocrystals to Hot Carrier Cooling Dynamics
Junzhi Ye, Navendu Mondal, Ben P. Carwithen +16
Defect tolerance is a critical enabling factor for efficient lead-halide perovskite materials, but the current understanding is primarily on band-edge (cold) carriers, with signifi…
Roadmap on Perovskite Light-Emitting Diodes
Ziming Chen, Robert L. Z. Hoye, Hin-Lap Yip +40
In recent years, the field of metal-halide perovskite emitters has rapidly emerged as a new community in solid-state lighting. Their exceptional optoelectronic properties have cont…
Direct Linearly-Polarised Electroluminescence from Perovskite Nanoplatelet Superlattices
Junzhi Ye, Aobo Ren, Linjie Dai +26
Polarised light is critical for a wide range of applications, but is usually generated by filtering unpolarised light, which leads to significant energy losses and requires additio…
Thickness-Dependence of Exciton-Exciton Annihilation in Halide Perovskite Nanoplatelets
Moritz Gramlich, Bernhard J. Bohn, Yu Tong +3
Exciton-exciton annihilation (EEA) and Auger recombination are detrimental processes occurring in semiconductor optoelectronic devices at high carrier densities. Despite constituti…
Identifying and reducing interfacial losses to enhance color-pure electroluminescence in blue-emitting perovskite nanoplatelet light-emitting diodes

Perovskite nanoplatelets (NPls) hold great promise for light-emitting applications, having achieved high photoluminescence quantum efficiencies (PLQEs) approaching unity in the blu…
Accelerated Carrier Relaxation through Reduced Coulomb Screening in 2D Halide Perovskite Nanoplatelets
Verena A. Hintermayr, Lakshminarayana Polavarapu, Alexander S. Urban +1
For high-speed optoelectronic applications relying on fast relaxation or energy transfer mechanisms, understanding of carrier relaxation and recombination dynamics is critical. Her…
Boosting tunable blue luminescence of halide perovskite nanoplatelets through post-synthetic surface trap repair
Bernhard J. Bohn, Yu Tong, Moritz Gramlich +9
The easily tunable emission of halide perovskite nanocrystals throughout the visible spectrum makes them an extremely promising material for light-emitting applications. Whereas hi…
Monitoring Galvanic Replacement Through Three-Dimensional Morphological and Chemical Mapping
Bart Goris, Lakshminarayana Polavarapu, Sara Bals +2
Galvanic replacement reactions on metal nanoparticles are often used for the preparation of hollow nanostructures with tunable porosity and chemical composition, leading to tailore…
Monolayer Graphene as Saturable Absorber in Mode-locked Laser
Qiaoliang Bao, Han Zhang, Zhenhua Ni +6
We demonstrate that the intrinsic properties of monolayer graphene allow it to act as a more effective saturable absorber for mode-locking fiber lasers compared to multilayer graph…
