Full Solution Process of a Near-Infrared Light-Emitting Electrochemical Cell Based on Novel Emissive Ruthenium Complexes of 1,10-Phenanthroline-Derived Ligands and a Eutectic Alloy as the Top Electrode
Near-infrared luminescent materials have recently received considerable attention for a large number of applications, including in solid-state lighting, as bioimaging agents, as photovoltaic cells, and in the telecommunication industry. By adding diverse e ...
AMER CHEMICAL SOC2023On the Response Speed of Narrowband Organic Optical Upconversion Devices
Frank Nüesch, Roland Hany, Surendra Babu Anantharaman, Matthias Diethelm, Wei-Hsu Hu
Organic upconversion devices (OUCs) consist of an organic infrared photodetector and an organic visible light-emitting diode (OLED), connected in series. OUCs convert photons from the infrared to the visible and are of use in applications such as process c ...
WILEY-V C H VERLAG GMBH2022Luminescent, porous, metal-organic crystals: Design, synthesis, and applications
The work presented in this thesis is focused on the design and discovery of new luminescent, porous, crystalline materials for targeted applications. In particular, we focus on luminescent Metal-Organic Frameworks (MOFs) and Organic Molecules of Intrinsic ...
EPFL2021Characterization and Modelling of the Emission Zone and Exciton Dynamics in Doped Organic Light-Emitting Diodes
Only recently organic light-emitting diode (OLED) technology has successfully managed the transition from research labs into the consumer market, taking a 60% share of the global mobile display market in 2018. The latest discovery of thermally activated de ...
EPFL2019Near-infrared absorbing cyanine dyes for all-organic optical upconversion devices
Roland Hany, Matthias Diethelm
The development of near-infrared (NIR) photodetection technologies is driven by emerging applications such as medical imaging or optical sensors for electronic displays and machine vision. An all-organic upconverter (OUD) is a device that converts incident ...
2019Tailored-Potential Semiconductor Quantum Nanostructures Grown in Inverted Pyramids
We have focused on the ability to tune the aluminum (Al) content of the AlGaAs alloy along the growth direction in inverted pyramids (by MOVPE), thus tailoring the potential along a QWR nanostructure. Three parabolic-potential QDs (PQDs) of different poten ...
EPFL2019Low-voltage, high-brightness and deep-red light-emitting electrochemical cells (LECs) based on new ruthenium(II) phenanthroimidazole complexes
Mohammad Khaja Nazeeruddin, Cristina Roldán Carmona
Light-Emitting Electrochemical Cells (LECs) with a simple device structure ITO/Ru complex/Ga: In were prepared by using heteroleptic ruthenium(II) complexes containing 2-(2-hydroxyphenyl)-1(4-bromophenyl)-1h-imidazo[4,5-f][1,10] phenanthroline (hpbpip) as ...
Royal Society of Chemistry2016Time-resolved X-ray and Optical Studies of Metalloproteins and Iridium Complexes
A wide variety of physicochemical processes at a molecular level, in particular charge or energy transfer, electronic and vibrational relaxation, are at the origin of biological functionality of proteins and organometallic compounds. The work reported in t ...
EPFL2015A Eu(III) Tetrakis(b-diketonate) Dimeric Complex: Photophysical Properties, Structural Elucidation by Sparkle/AM1 Calculations, and Doping into PMMA Films and Nanowires
Rosario Scopelliti, Jean-Claude Bünzli
Reaction of Ln(III) with a tetrakis(diketone) ligand H4L [1,1?-(4,4?-(2,2-bis((4-(4,4,4-trifluoro-3-oxobutanoyl) phenoxy)methyl)propane-1,3-diyl)bis(oxy)bis(4,1-phenylene))bis(4,4,4-trifluorobutane-1,3-dione)] gives new podates which, according to mass spe ...
American Chemical Society2014Charged Bis-Cyclometalated Iridium(III) Complexes with Carbene-Based Ancillary Ligands
Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Julien Edouard Frey
Charged cydometalated (CN) iridium(III) complexes with carbene-based ancillary ligands are a promising family of deep-blue phosphorescent compounds. Their emission properties are controlled primarily by the main CN ligands, in contrast to the classic ...
