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…
Control of electronic band profiles through depletion layer engineering in core-shell nanocrystals
Michele Ghini, Nicola Curreli, Matteo B. Lodi +6
The understanding of depletion layers is of major importance to control the optical and electronic properties of metal oxide (MO) nanocrystals (NCs). Here, we show that depletion l…
Temporal Evolution of Self-Assembled Lead Halide Perovskite Nanocrystal Superlattices: Effects on Photoluminescence and Energy Transfer
Dmitry Baranov, Antonio Fieramosca, Ruo Xi Yang +8
Excitonic/electronic coupling and cooperative interactions in self-assembled lead halide perovskite nanocrystals were reported to give rise to a collective low energy emission peak…
Temperature Driven Transformation of CsPbBr Nanoplatelets into Mosaic Nanotiles in Solution through Self-Assembly
Zhiya Dang, Balaji Dhanabalan, Andrea Castelli +9
Two-dimensional colloidal halide perovskite nanocrystals are promising materials for light emitting applications. In addition, they can be used as components to create a variety of…
Single-mode lasing from colloidal water-soluble CdSe/CdS quantum dot-in-rods
Francesco Di Stasio, Joel Q Grim, Vladimir Lesnyak +4
Core-shell CdSe/CdS nanocrystals are a very promising material for light emitting applications. Their solution-phase synthesis is based on surface-stabilizing ligands that makes th…
