Optical properties of a periodic one-dimensional semiconductor-organic photonic crystal in UV region

Optical properties of a one-dimensional semiconductor-organic photonic crystal with periodic AlN/3-octylthiophenes (P3OT) multilayer structure are exhibited and confirmed by a calculation of the transfer matrix method (TMM). An AlN/P3OT multilayer structure displays incomplete photonic band gap behavior in the UV region. The AlN/P3OT multilayers with four pairs of 35-nm-AlN and 35-nm-P3OT layers exhibit a high reflectivity of 89% and less absorption of 10% at a wavelength of about 300 nm. These results demonstrate the AlN/P3OT multilayer structure could be a good candidate for absolute inhibition of reflection in the ultraviolet region for a given orientation.
