Abstract

We have prepared pentacene films on Si, A1 2 O 3 , and glass substrates by thermal evaporation and have investigated their optical properties at room temperature over a wide range of frequencies from infrared to ultraviolet (5 meV to 6.5 eV). A series of optical phonon modes and electronic transitions have been observed. The internal vibrational modes in the infrared region match well their molecular counterparts but the electronic transitions show substantial changes from those of a free pentacene molecule. The HOMO-LUMO gap energy of the pentacene films deposited on A1 2 O 3 and glass substrates is 1.85 eV.
