We report on transmission and reflectance spectra of fullerite C-60 thin films deposited on quartz substrate. An Urbach tail of states is present below the absorption edge due to the disordered structure of the films. Photoluminescence (PL) spectra have been measured from 10 to 300 K. Recombination of self-trapped excitons and their phonon replicas are present in the PL spectra. Temperature dependence of the integrated intensity of each emission line is also reported.

Abstract
We report on transmission and reflectance spectra of fullerite C-60 thin films deposited on quartz substrate. An Urbach tail of states is present below the absorption edge due to the disordered structure of the films. Photoluminescence (PL) spectra have been measured from 10 to 300 K. Recombination of self-trapped excitons and their phonon replicas are present in the PL spectra. Temperature dependence of the integrated intensity of each emission line is also reported.
