PHOTOLUMINESCENCE CHARACTERISTICS AND GROWTH-OF TEXTURED C60 FILMS

Abstract

The (111) textured C60 films have been fabricated on the fluorophlogopite crystal by hot wall method. X-ray diffraction patterns and Raman spectrum of C60 films indicate that the C60 film is in fcc structure,and tends to have a (111) texture. The surface structure and the crystal morphology of C60 films are measured by scanning electron microscopy and atomic force microscopy. At 77K and 300K,photoluminescence spectra of the textured C60 films are measured. And radiative mechanisms are discussed.
