Abstract
The photoluminescence spectra and quantum yield of ?-sexithienyl (T 6) thin films grown in high vacuum have been measured at different temperatures in the range 30K-300K. The measurements have been performed with a home-built experimental apparatus based on an integrating sphere, which allows luminescence spectra and quantum yield measurements in the temperature range 5K-400K. The analysis of the photoluminescence spectra allows to identify the spectral contribution from molecular ...File in questo prodotto:
