Abstract
We report on transmission and reflectance spectra of fullerite C-60 th in films deposited on quartz substrate. An Urbach tail of states is pr esent below the absorption edge due to the disordered structure of the films. Photoluminescence (PL) spectra have been measured from 10 to 3 00 K. Recombination of self-trapped excitons and their phonon replicas are present in the PL spectra. Temperature dependence of the integrat ed intensity of each emission line is also reported.
