Investigation of temperature dependence of photoluminescence for fluorinated fullerene thin films
چکیده انگلیسی
Temperature dependences of photoluminescence spectra of C60F18 and C60F24 thin films have been investigated in the range of T=15-300K. It was established that these spectra of C60F2x compounds strongly vary with temperature. The like behavior could be related to a phase transition of the ferro-electric type with TC∼150-200 K. The reflectivity of C60F18 measured at T=10-300K manifested a temperature change of peak positions and shape. These experiments support the idea of a phase transition at TC. The luminescence excitation spectra of C60F2x compounds demonstrate changes due to fluorination of the C60 skeleton.
