  2. Contact: Raphael.pugin@csem.ch Guy.voirin@csem.ch Project Idea: Supramolecular assembly for lighting and displayEU call: NMK 17 - 2014 Project Idea short description: Highly efficient color display / lighting using supramolecular assembly with unique properties (j-aggregate) Short Description: J-aggregates allow loss-free delocalisation of excitation energy over long distances and therefore provide high efficiency for energy transfer. Combined with different quantum dots enhanced emission (x10) was demonstrated. Highly efficient color display based on blue LED and LED lighting IP situation and commercial viability: Two CSEM patents and one patent application Compatible with industrial large area coating process (curtain coating, slot die, dipping, printing) Potential Applications / Applications: LED display LED lightning Sensing (superquenching effect) Potential Consortium/Competences needed: Firm 1: display/lighting company RTO: display/lighting development CSEM: supramolecular assembly, upscaling

  3. Enhanced QDs emission (x10) due to FRET Demonstrated for several QDs (excitation with blue LED, emission in red or green) Very high potential for lighting and displays application domains Highly emitting colour changing films

  5. Contact: Ross.stanley@csem.ch Guy.voirin@csem.ch Project Idea: Improved biochemical sensing using nanophotonic structuresEU call: ICT 26 – 2014: Photonics KET Project Idea short description: Use nanostructuration to realise multifunctional sensing surface for diagnostic instrumentation: application to cancer detection in breath Short Description: nanophotonic structures are highly sensitive to change in refractive index, nanostructuration enhance fluorescence signal, porous membranes enhance binding efficiency. Nanostructuration can be made by combining self assembly with microfab. Detection of cancer biomarkers (VOC, protein, DNA,…) in breath using an array of photonic structures interrogated by a camera IP situation and commercial viability: To be check Potential Applications / Applications: Low power, High throughput, Disposable, Compatible with mobile phone Potential Consortium/Competences needed: Firm 1: diagnostic instrumentation company Firm 2 : medical research RTO: specific functionalisation, transducer surface fabrication, specific electronic CSEM: modelisation, design, readout system, integration,
