Ultrafast Dynamics and Laser Action of Organic SemiconductorsAuthor(s): Zeev Valy Vardeny\nFormat: Hardback\nPublisher: Taylor & Francis Inc, United States\nImprint: CRC Press Inc\nISBN-13: 9781420072815, 978-1420072815\nSynopsis\nSpurred on by extensive research in recent years, organic semiconductors are now used in an array of areas, such as organic light emitting diodes (OLEDs), photovoltaics, and other optoelectronics. In all of these novel applications, the photoexcitations in organic semiconductors play a vital role. Exploring the early stages of photoexcitations that follow photon absorption, Ultrafast Dynamics and Laser Action of Organic Semiconductors presents the latest research investigations on photoexcitation ultrafast dynamics and laser action in pi-conjugated polymer films, solutions, and microcavities.\n\nIn the first few chapters, the book examines the interplay of charge (polarons) and neutral (excitons) photoexcitations in pi-conjugated polymers, oligomers, an.
