Colloidal quasi-2D Methylammonium Lead Bromide Perovskite Nanostructures with Tunable Shape and High Chemical Stability
Eugen Klein, Rostyslav Lesyuk, Christian Klinke
Control over the lateral dimensions of colloidal nanostructures is a complex task which requires a deep understanding of the formation mechanism and reactivity in the corresponding…
Tailoring Charge Donor-Acceptor Interaction in CsPbBr3 Perovskite Nanocrystals through Ligand Exchange
Syed Abdul Basit Shah, Sushant Ghimire, Rostyslav Lesyuk +3
The surface ligands in colloidal metal halide perovskites influence not only their intrinsic optoelectronic properties but also their interaction with other materials and molecules…
New approach for obtaining ceramic NASICON (NaZr (SiO)PO) films sintered in situ by a sol-gel method, using spray deposition and Near-Infra Red Sintering
Rafael Marti Valls, Rebecca Griffin, Anne Sawhney +5
In this work we demonstrate a NASICON film sintered in situ onto a fused silica substrate. This production method drastically reduces the manufacturing time by combining the use of…
Synthesis, Optoelectronic Properties, and Charge Carrier Dynamics of Colloidal Quasi-two-dimensional Cs3Bi2I9 Perovskite Nanosheets
Sushant Ghimire, Chris Rehhagen, Saskia Fiedler +3
Non-toxicity and stability make two-dimensional (2D) bismuth halide perovskites better alternatives to lead-based ones for optoelectronic applications and catalysis. In this work,…
Role of Magnetic Coupling in Photoluminescence Kinetics of Mn2+-doped ZnS Nanoplatelets
Liwei Dai, Abderrezak Torche, Christian Strelow +8
Mn2+-doped semiconductor nanocrystals with tuned location and concentration of Mn2+ ions can yield diverse coupling regimes, which can highly influence their optical properties suc…
Colloidal two-dimensional metal chalcogenides: Realization and application of the structural anisotropy
Ziyi Hu, Ryan O'Neill, Rostyslav Lesyuk +1
Due to the spatial confinement, two-dimensional metal chalcogenides display an extraordinary optical re-sponse and carrier transport ability. Solution-based synthesis techniques su…
