2. 1. Synthesis of Conjugated Polymers and Small Molecules for Organic Light-Emitting Devices and Photodetectors

   Author : Petri Henrik Murto; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solution processing; conjugated polymers; fluorescence; near-infrared; light-emitting electrochemical cell; organic photodetector; organic light-emitting diode;

   Abstract : Production cost and environmental impact are the two major concerns that are related to the conventional optoelectronic devices. It is desirable for the modern semiconductors that they are free of toxic/costly metals, they can be processed with low-cost solution-based methods, and their optical, electronic, and mechanical properties can be easily tuned depending on the target application.

4. 2. Inorganic-Organic Hybrid Technology for Light Emitting Diodes

   Author : Amal Wadeasa; Magnus Willander; Omer Nour; Rose-Marie Mikström; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Since the first report of inorganic light emtting diodes a century ago the field of inorganic light emitting diodes has evolved rapidly. T he development of light emitting diodes technology has caused their efficiency and light output to increase exponentially, with a doubling occuring about every 36 months  since the 1960s, in a similar way to Moor´s law.

5. 3. Studies of Materials and Interfaces for Organic Electronics

   Author : Slawomir Braun; William R. Salaneck; Ian McCulloch; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic electronic; Polymeric materials; Organic light-emitting diodes OLEDs ; Organic fieldeffect transistors OFETs ; Organic solar cells; Material physics with surface physics; Materialfysik med ytfysik;

   Abstract : Organic electronics is a rapidly evolving field with vast number of applications having high potential for commercial success. Although a great progress has been made, many organic electronic applications: organic light-emitting diodes (OLEDs), organic fieldeffect transistors (OFETs), organic solar cells, etc; still require further optimization to fulfill the requirements for successful commercialization.

6. 4. Light-Emitting Electrochemical Transistors

   Author : Jiang Liu; Magnus Berggren; Isak Engquist; Qibing Pei; Linköpings universitet; []
   Keywords : ;

   Abstract : Since the discovery of conductive polymers in 1977, the implementation of organic conjugated materials in electronic applications has been of great interest in both industry and academia. The goal of organic electronics is to realize large-area, inexpensive and mechanically-flexible electronic applications. READ MORE

7. 5. Interface-Assisted Perovskite Modulations for High-Performance Light-Emitting Diodes

   Author : Chaoyang Kuang; Feng Gao; Sai Bai; Niclas Solin; Olle Inganäs; Mingjian Yuan; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal halide perovskite; Light-emitting diodes; Deprotonation; Interfacial reaction; Additive; Molecular interactions; Metall-halid-perovskiter; Lysdioder; Deprotonering; Gränsytegenererade reaktion; Tillsatsämnen; Molekylära interaktioner;

   Abstract : Metal halide perovskites have emerged as a class of promising materials for a wide range of optoelectronic devices. Compared with traditional inorganic and organic semiconductors, perovskite materials can be easily processed via solution-based techniques at low temperatures and exhibit high photo-luminescence efficiency, outstanding colour purity, and superior charge transport properties, showing great promise for cost-effective and high-performance light-emitting diodes (LEDs).
