Quantum-mechanical effects in photoluminescence from thin crystalline gold films

Giulia Tagliabue, Fateme Kiani Shahvandi, Alan Richard Bowman, Theodoros Tsoulos

Luminescence constitutes a unique source of insight into hot carrier processes in metals, including those in plasmonic nanostructures used for sensing and energy applications. However, being weak in nature, metal luminescence remains poorly understood, its ...

Soft bioelectronic technologies for selective and multimodal peripheral nerve interfaces

Valentina Marie Paggi

The peripheral nervous system (PNS) regulates the exchange of sensory information andmotor commands between the body and the central nervous system. Further, through theautonomic nervous system, the PNS plays a pivotal role in controlling vital physiologic ...

A neural probe to sample brain fluid in nanoliter volumes for quantitative molecular studies

Joan Teixidor

Neural functions operate in tightly controlled conditions that are mediated by multiple electrical and chemical phenomena. Brain disorders such as Parkinson's Disease and Alzheimer's Disease perturb these conditions and cause a loss of neurons, which impai ...

Spectrometer-free electron probe of ultrafast thermal dynamics in optically excited samples

Fabrizio Carbone

Cutting edge electron microscopes allow to probe the optical excitations in nanostructures with subangstrom spatial and femtosecond temporal resolution. In this study we discuss the prospects of probing the ultrafast out-of-equilibrium dynamics of plasmoni ...

Gigahertz Frame Rate Imaging of Charge-Injection Dynamics in a Molecular Light Source

Klaus Kern, Markus Etzkorn, Anna Maria Roslawska, Abhishek Grewal

Light sources on the scale of single molecules can be addressed and characterized at their proper sub-nanometer scale by scanning tunneling microscopy-induced luminescence (STML). Such a source can be driven by defined short charge pulses while the lumines ...

Sensitisation of visible and NIR lanthanide emission by InPZnS quantum dots in bi-luminescent hybrids

Marinella Mazzanti

The synthesis of stable hybrid nanoparticles combining InPZnS@ZnSe/ZnS quantum dots (QDs) and grafted lanthanide complexes has been performed using two different approaches in organic and aqueous media. The final bi-luminescent hybrids exhibit Ln(III) (Ln ...

Guidelines for Measurement of Luminescence Spectra and Quantum Yields of Inorganic Compounds, Metal Complexes, and Materials

Jean-Claude Bünzli

Guidelines for measuring luminescence of inorganic compounds, metal complexes and organometallic compounds are described. Common textbooks and manuals describing these measurements are usually aimed for physical and/or organic chemists and are not always s ...

The Impact of Porosification upon Luminescence of HVPE Grown GaN and the Influence of the Porous Layer upon the Quality of the Overgrown GaN Film

Nicolas Grandjean, Jean-François Carlin, Denis Martin

In this paper, we show that the quality of the porous layers produced by photoelectrochemical (PEC) etching of HVPE GaN in oxalic acid is better than that of the initial material, and the quality of GaN films overgrown on porous layers can be improved by a ...
