XANES and EXAFS studies have been carried out on Fe doped ZnO thin films having different Fe doping concentration ranging from 1% to 10% and the observed ferromagnetism in the samples is explained in the light of XANES and EXAFS observations.
1,2,3,4-Tetrafluoro-dinaphthothienothiophene
(F4DNTT) and 1,2,3,4,8,9,10,11-octafluoro-dinaphthothienothiophene
(F8DNTT) were synthesized via bisthiomethyl alkene intermediates which
were accessible by McMurry coupling or Wittig olefination of partially
fluorinated naphthalene precursors. DFT-based electronic structure
calculations, X-ray absorption spectroscopy (NEXAFS) and UV/Vis
measurements were used for HOMO/LUMO gap determination and to analyse
the electronic structures of the partially fluorinated DNTTs. Reduced
exciton binding was observed in thin films
