Improving the Stability of Colloidal CsPbBr3 Nanocrystals with an Alkylphosphonium Bromide as Surface Ligand Pair
Meenakshi Pegu, Hossein Roshan, Clara Otero-Martinez +9
In this study, we synthesised a phosphonium-based ligand, trimethyl(tetradecyl)phosphonium bromide (TTP-Br), and employed it in the post-synthesis surface treatment of Cs-oleate-ca…
Size-dependent multiexciton dynamics governs scintillation from perovskite quantum dots
Andrea Fratelli, Matteo L. Zaffalon, Emanuele Mazzola +10
The recent emergence of quantum confined nanomaterials in the field of radiation detection, in particular lead halide perovskite nanocrystals, offers potentially revolutionary scal…
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…
