Abstract

ABSTRACTNanoporous Cu4O3 – C composite thin films with spherical and bicontinuous elongated pore structure have been grown on stainless steel substrates by metalorganic chemical vapour deposition technique using a single source tetranuclear metalorganic complex as precursor. The guiding and confinement of light in these quasi-periodic structures has been investigated by glancing incidence (75°) infrared spectroscopy at room temperature. The transmittance spectra of these films between wave number 10000 – 400 cm−1 reveal light confinement modes in photonic band gap between 6127-8839 cm−1 and propagation modes between 5094-400 cm−1.
