Optical properties in 2D photonic crystal structure using fullerene and azafullerene thin films

Theoretical calculations via a transfer matrix method were performed to investigate the possibility of fullerene films acting as two-dimensional (2D) photonic band gap crystals. The response within and out of the periodic structure of 2D photonic crystals consisting of air rods drilled into C60 or (C59N)2 films was studied. PBG was found around 0.85-1.24 eV in the near infrared region. We find that fullerene-based networks could be good candidates for absolute inhibition of transmission in the near infrared range for given orientations.
