Abstract :
For the first time optical investigations of C60F18 single crystals were carried out in the temperature region (300–4) K. Intensity of the obtained photoluminescence (PL) spectra has a strong brake near 100 K. At low temperature the clear fine structure of luminescence spectra is observed. The reflectance spectra have shown main changes for the energy about 4 eV (typical for π–π* transitions), and for E> 8 eV for deeper electronic levels.
