Direct Observation of Shallow Trap States in Thermal Equilibrium with Band‐Edge Excitons in Strongly Confined CsPbBr 3 Perovskite Nanoplatelets

Jacques-Edouard Moser, Etienne Christophe Socie, Andrés Burgos Caminal, Brener Rodrigo De Carvalho Vale

Lead halide perovskites exhibit great potential for light-emitting devices. Enhanced photoluminescence (PL) is obtained in perovskite materials of reduced dimensionalities due to the large exciton binding energy. However, as the nanocrystal size is reduced ...

Exciton-Carrier Dynamics in 2D Perovskites

Jacques-Edouard Moser, Etienne Christophe Socie, Marine Eva Fedora Bouduban, Andrés Burgos Caminal

2D perovskites has become a major topic in the field of perovskite optoelectronics. Here, we aim to unravel the ultrafast dynamics governing the evolution of charge carriers and excitons. We use a combination of ultrabroadband time-resolved THz spectroscop ...

Phenanthrene-Fused-Quinoxaline as a Key Building Block for Highly Efficient and Stable Sensitizers in Copper-Electrolyte-Based Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Etienne Christophe Socie, Weiwei Zhang, Brian Irving Carlsen, Yinghui Wu, Yameng Ren, Huiyun Jiang

Dye-sensitized solar cells (DSSCs) based on Cu-II/I bipyridyl or phenanthroline complexes as redox shuttles have achieved very high open-circuit voltages (V-OC, more than 1 V). However, their short-circuit photocurrent density (J(SC)) has remained modest. ...

Exciton and Carrier Dynamics in Two-Dimensional Perovskites

Jacques-Edouard Moser, Etienne Christophe Socie, Marine Eva Fedora Bouduban, Andrés Burgos Caminal

Two-dimensional Ruddlesden−Popper hybrid lead halide perovskites have become a major topic in perovskite optoelectronics. Here, we aim to unravel the ultrafast dynamics governing the evolution of charge carriers and excitons in these materials. Using a com ...

Exciton, Biexciton, and Hot Exciton Dynamics in CsPbBr3 Colloidal Nanoplatelets

Jacques-Edouard Moser, Etienne Christophe Socie, Andrés Burgos Caminal, Brener Rodrigo De Carvalho Vale

Lead halide perovskites have emerged as promising materials for light-emitting devices. Here, we report the preparation of colloidal CsPbBr3 nanoplatelets (3 × 4 × 23 nm3) experiencing a strong quasi-one-dimensional quantum confine- ment. Ultrafast transie ...

Enhanced Intersystem Crossing and Transient Electron Spin Polarization in a Photoexcited Pentacene–Trityl Radical

David Lyndon Emsley, Jacques-Edouard Moser, Aaron James Rossini, Dominik Józef Kubicki, Moreno Lelli, Etienne Christophe Socie, Gabriele Stevanato, Claudia Esther Avalos

Identifying and characterizing systems that generate well-defined states with large electron spin polarization is of high interest for applications in molecular spintronics, high-energy physics, and magnetic resonance spectroscopy. The generation of electr ...

Revealing Exciton and Metal–Ligand Conduction Band Charge Transfer Absorption Spectra in Cu-Zn-In-S Nanocrystals

Jacques-Edouard Moser, Etienne Christophe Socie, Brener Rodrigo De Carvalho Vale

Copper indium sulfide quantum dots (QDs) have attracted substantial attention in recent years due to environmental issues and diverse applications. We report the synthesis and characterization of copper-zinc-indium-sulfide (CZIS) QDs and CZIS treated with ...

Measuring Nano- to Microstructures from Relayed Dynamic Nuclear Polarization NMR

David Lyndon Emsley, Aaron James Rossini, Moreno Lelli, Arthur César Pinon, Pierrick Berruyer, Etienne Christophe Socie, Judith Schlagnitweit

We show how dynamic nuclear polarization (DNP) NMR can be used in combination with models for polarization dynamics to determine the domain sizes in complex materials. By selectively doping a source component with radicals and leaving the target undoped, w ...
