"We show that the presence of silver vacancies results in the redemission (650 nm) with an activated temperature dependence, whereas the blue emission (425 nm) stems from the lecithin lig-ands spectrally overlapping with the plasmon resonance of thesurface-attached Ag nanoclusters."

"The Bunsen Magazine is the members' magazine of the German Bunsen Society and also an important specialist publication on topics in physical chemistry. It has been published under this name since 1999 and reports on current and relevant developments in the fields of physical chemistry, the activities of the DBG, the job market and much more.."

"Every year, CeNS awards prizes for excellent publications of CeNS members which have been published during the past 12 months. With this award, remarkably successful cooperation projects within CeNS as well as outstanding research of an individual research group of CeNS were distinguished."

"The Nobel Prize in Chemistry 2023 rewards the discovery and development of quantum dots,nanoparticles so tiny that their size determines theirproperties. These smallest components of nanotechnology now spread their light from televisions andLED lamps, and can also guide surgeons when they remove tumour tissue, among many other things."

"Herein, we study this interaction based on the controlled PL quenching of CsPbBr3-QDs with BiBr3. Based on the so-called sphere of action model for the adsorption process, we show that already a single BiBr3 adsorption suffices to completely quench a QD’s luminescence. This approach is expanded to analyze size-, ligand-, and metal-dependent quenching dynamics.  "

"The mission of CeNS is to promote and coordinate interdisciplinary research in the field of nanoscience in the Munich area. CeNS is an association of junior and senior scientists from basic research and industry and is conceived as a network, joining people from various institutions (LMU, TU Munich, University of Augsburg and others)."

"We report new insights into the nucleation, growth, and self-assembly in this reaction, obtained by in situ synchrotron-based small-angle X-ray scattering and optical absorption spectroscopy. We show that dispersed 3 nm Cs[PbBr3] agglomerates are the key intermediate species: first, they slowly nucleate into crystals, and then they release Cs[PbBr3] monomers for further growth of the crystals."

"Here, we introduce the soluble fullerene derivative PC60BM as an electron acceptor along with CsPbI3 to create an imbalance between the photoexcited electrons and holes in the NCs and, thus, affecting their spin-dependent carrier distribution. We ascribe the fast electron spin relaxation to the presence of strong spin–orbit coupling in the conduction band, which is ineffective for holes in the s-type valence band. "

"We show that for spherical-like CsPbBr3 QDs with diameters >6 nm, excitons confine with respect to their center-of-mass motion leading to well-pronounced resonances in their absorption spectra. The temporal dynamics of the bleached excitons further support our exciton confinement model. Our study provides the first insight into confined excitons in CsPbBr3 QDs and gives a detailed understanding of their linear and nonlinear optical spectra."

"In this work, monodisperse spheroidal CsPb(Cl:Br)3 QDs are synthesized in the 4–10 nm range, at any Cl:Br ratio, with up to five excitonic absorption transitions. Furthermore, in situ spectroscopy was used to cross-correlate the size and composition of these QDs directly to the energy of the first two excitonic absorption transitions.  "

"Inorganic materials with more covalent bonding, such as cadmium selenide, form uniform nanoparticles under fast growth conditions, but perovskites such as cesium lead bromide (CsPbBr3) are more ionic and grow rapidly to form larger nanoparticles. Akkerman et al. controlled the nanoparticles’ growth kinetics by using trioctylphosphine oxide, which solubilized the PbBr2 precursor, bound to the cation-[PbBr3] monomer (solute), and weakly coordinated to the crystal nuclei surfaces. Nanoparticles with diameters from 3 to 13 nanometers were stabilized and isolated in high yield with lecithin, a long-chain zwitterion. Four well-resolved excitonic transitions with size-dependent confinement energies were seen for cesium as well as organic cations. "
