DESCRIPTION:Abstract: \n\n \n\nOrganic semiconductors are remarkable carbon
 -based materials that combine novel semiconducting optoelectronic properti
 es with simple processing. They can be used to make printed and flexible e
 lectronics\, and their properties (e.g. colour) can be tuned by changing t
 heir chemical structure. Organic light-emitting diodes (OLEDs) are compact
  visible light sources that are now found across the world in mobile phone
  displays and televisions. This talk will give an introduction to organic 
 semiconductors and optoelectronic devices made from them.\n	It will then ex
 plore two emerging fields of application. The first is photodynamic therap
 y (PDT). In PDT light in combination with a light-activated chemical leads
  to the generation of reactive oxygen species. OLEDs are very attractive l
 ight sources for PDT because they emit over an area\, are thin and potenti
 ally flexible We have shown that PDT with OLEDs can kill skin cancer\, par
 asites and bacteria. Another emerging application is in visible light comm
 unication (or Li-Fi) in which light is modulated to encode information to 
 supplement Wi-Fi. Finally a new organic optoelectronic device – a laser el
 ectrically driven by an OLED will be presented.\n\n \n\nBio:\n\nIfor Samue
 l is Professor of Physics at the University of St Andrews. He received his
  MA and PhD from the University of Cambridge\, working on optical spectros
 copy of organic semiconductors. He was a Research Fellow at Christ’s Colle
 ge\, Cambridge and also performed postdoctoral work at CNET-France Telecom
  in Paris\, before setting up his own research group on light-emitting pol
 ymers at the University of Durham. In 2000 he moved to the University of S
 t Andrews where he founded and leads the Organic Semiconductor Centre. His
  current work concerns the photophysics of organic semiconductor materials
  and devices including organic light-emitting diodes\, solar cells\, laser
 s and their applications\, and he has published over 500 journal papers. H
 e is a Fellow of the Royal Society of Edinburgh\, the Institute of Physics
 \, SPIE and the Royal Society of Chemistry.\n
