Shortwave Infrared-Sensitive, Narrowband Organic Upconversion Devices with a Gain
Sensing and imaging of light in the shortwave infrared (SWIR) range is increasingly used in various fields, including bio-imaging, remote sensing, and semiconductor process control. SWIR-sensitive organic photodetectors (OPDs) are promising because organic ...
EPFL2024On 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 GMBH2022Ion and Trap Induced Dynamic Phenomena in Salt Semiconductor Devices
State-of-the-art organic light-emitting diodes (OLEDs) used in commercial display technology are complex multilayer structures. In contrast, the light-emitting electrochemical cell (LEC) can be built from a single emissive layer sandwiched between two elec ...
EPFL2021Synthesis of NIR-Absorbing Squaraine Dyes and their Use in Organic Upconversion Devices
Squaraines are organic dyes showing the advantages of a simple synthesis, high absorption coefficients and tunable bandgaps from the visible to the near-infrared (NIR) region. Their molecular structure is based on a polymethine chain and a donor-acceptor-d ...
EPFL2021Design of a compliant load cell with adjustable stiffness
Charles Baur, Lennart Rubbert, Michal Stanislaw Smreczak
Manipulation at the sub-micron scale often requires force-sensing capabilities of milli-to nanonewton forces. This article presents a novel design of a compliant load cell with mechanically adjustable stiffness. The system enables adapting force sensitivit ...
ELSEVIER SCIENCE INC2021Taking a snapshot of the triplet excited state of an OLED organometallic luminophore using X-rays
Andrea Cannizzo, Giulia Fulvia Mancini, Camila Bacellar Cases Da Silveira, Martin Beck, Victoria Kabanova, Samuel Menzi
OLED technology beyond small or expensive devices requires light-emitters, luminophores, based on earth-abundant elements. Understanding and experimental verification of charge transfer in luminophores are needed for this development. An organometallic mul ...
NATURE PUBLISHING GROUP2020NOVEL TRIAZENES AND SOLID STATE LUMINOGENS
Triazenes are very useful compounds in organic synthesis, materials science, and medicine. Among numerous reported triazene derivatives, aryl triazenes are the most investigated. Triazenes with alkynyl, vinyl, and alkyl groups were, until recently, largely ...
EPFL2020Optimized Design of Silicon Heterojunction Solar Cells for Field Operating Conditions
Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa, Olivier Denis Dupré
Solar modules are currently characterised at standard test conditions (STC), defined at 1000 W/m2 and 25 °C. However, solar modules in actual outdoor operating conditions typically operate at lower illumination and higher temperature than STC, which signif ...
2019A Rendering Solution to Display Light Field in Virtual Reality
Touradj Ebrahimi, Evgeniy Upenik, Irene Viola
There is a need for affordable and easily deployable rendering and display solutions to take full advantage of light field imaging. In particular, the research community needs ways to better assess the impact of various light field imaging technologies bas ...
