1. 11. Photo-polymerization as a tool for engineering the active material in organic field-effect transistors

   Författare :Andrzej Dzwilewski; Ludvig Edman; Xavier Crispin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Field-effect transistor; photo-polymerization; PCBM; C60; Fullerene; Physics; Fysik; fasta tillståndets fysik; Solid State Physics;

   Sammanfattning : The emergence of organic semiconductors is exciting since it promises to open up for straightforward and low-cost fabrication of a wide range of efficient and novel electronic devices. However, in order for this promise to become reality it is critical that new and functional fabrication techniques are developed. LÄS MER

   Författare :Jimmy W. P. Bakker; Hans Arwin; Jin Gang; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical sensing; Biohttps: www.diva-portal.org liu webform form.jsp#paper0sensing; Ellipsometry; Computer Screen Photo-assisted Technique; Fluorescence; Immunoassays; Optics; Optik;

   Sammanfattning : Two main subjects, ellipsometry and computer screen photo-assisted techniques (CSPT), form the main line in this thesis. Ellipsometry is an optical technique based on the detection of polarization changes of light upon interaction with a sample. LÄS MER

5. 14. Photo-induced dark states influorescence spectroscopy – investigations & applications

   Författare :Andriy Chmyrov; Jerker Widengren; Johan Hofkens; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence correlation spectroscopy; triplet state; isomerisation; photobleaching; quenching; diffusion; total internal reflection; interface; Spectroscopy; Spektroskopi;

   Sammanfattning : This thesis focuses on investigations of transient dark states of fluorescentmolecules using spectroscopic techniques. The main purpose is to show andconvince the reader that transient dark states are not always a nuisance, butalso represent an additional source of information. LÄS MER

7. 15. Ultrafast Photo-induced Reaction Dynamics of Small Molecules

   Författare :Malin Kadi; Jan Davidsson; Eva Åkesson; Sören Keiding; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; pump-probe spectroscopy; reaction dynamics; photodissociation; aryl halides; spin-orbit coupling; ab initio calculations; molecular dynamics; vibrational wavepackets; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : The main focus of this thesis is the investigation of the dissociation dynamics of aryl halides using femtosecond pump-probe spectroscopy. In the monohalogenated aryl halides, iodo-, bromo- and chlorobenzene, the rate of dissociation following excitation at 266 nm in the gas phase increased with increasing mass of the halogen atom.
